I run three weekly games across two different systems. My shelves hold rulebooks for a dozen more. And every year, the same question comes up in my gaming groups: "What should we play next?"
It's a better question than it used to be. The TTRPG market is projected to reach $5.11 billion by 2033, growing at 11.84% annually. More systems, more players. But popularity data tells us something useful about which systems have staying power and which are flash-in-the-pan hype.
These rankings draw from the January 2025 Compare The Market survey, Roll20's Orr Report (the most recent published edition), convention attendance data, and subreddit activity. No ranking is perfect, but triangulating across multiple data sources gives us a more honest picture than any single metric.
If you're a GM deciding which system to run next or a player curious about what's out there, this breakdown goes beyond "it's popular" to explain why each system earned its spot and what it actually feels like at the table.
1. Dungeons & Dragons 5e (2024 Rules Revision)
Market Share: Estimated 40-50% of total TTRPG market (Compare The Market, 2025) Roll20 Usage: Over 50% of all campaigns on the platform (Orr Report Q4 2021)
D&D tops every popularity metric for a reason that has nothing to do with game design: network effects. Your players have heard of it. YouTube has thousands of hours of tutorials. Every game store runs Adventurers League nights. When a new player asks "how do I start playing TTRPGs?" the answer is almost always D&D, and that creates a self-reinforcing cycle.
The 2024 rules revision (originally branded "One D&D" during playtest, but officially just "D&D 2024") refined the core system without breaking backward compatibility. The updated Player's Handbook reorganized subclasses, improved feat design, and cleaned up some rules ambiguities that had plagued 5e since 2014. D&D Beyond remains the best-integrated digital character tool in the hobby.
D&D's dominance also means it absorbs criticism that niche systems avoid. Combat can drag at higher levels. The CR system for encounter balancing is notoriously unreliable. And the system's flexibility means two D&D tables can feel like completely different games, which is both a strength and a source of confusion for new GMs.
Best For: New players entering the hobby, groups wanting maximum community support, GMs who value extensive published adventure modules
2. Pathfinder 2e
Market Share: Consistent second place across survey and sales data Key Advantage: Complete rules available free at Archives of Nethys
Pathfinder 2e earned its position by being the system D&D players graduate to when they want more tactical depth. The three-action economy is the single best combat innovation in mainstream fantasy TTRPGs: every turn, you get three actions, and you decide how to spend them. Move, Strike, Cast a Spell, Raise a Shield, Demoralize an enemy. The choices feel meaningful in a way that D&D's action/bonus action/movement split often doesn't.
Character building in PF2e is where the system truly shines. Class feats, ancestry feats, skill feats, and general feats at staggered levels mean two fighters can play completely differently. A champion who emphasizes divine magic and party protection plays nothing like a champion built around offensive strikes. The system gives you granular control without the trap options that plagued Pathfinder 1e.
Paizo's Organized Play program (Pathfinder Society) provides a steady pipeline of one-shot adventures and a community that actively welcomes new players. And since the OGL controversy in 2023, Pathfinder has operated under the ORC License, giving third-party creators more freedom to publish compatible content.
The trade-off: PF2e has more rules to learn upfront than D&D 5e. Character creation takes longer. And the tight math means GMs need to balance encounters more carefully. A +2 level difference between party and monster matters a lot more here than in 5e.
Best For: Players who love tactical combat puzzles, character-build theorycrafters, groups frustrated by D&D's looser balance
3. Call of Cthulhu (7th Edition)
Market Share: Third place globally, second in Japan and several European markets System: Percentile-based (d100), skill-driven
Call of Cthulhu has been in continuous publication since 1981. Forty-four years. That longevity alone tells you something about the design. While other horror games have come and gone, CoC's core loop (investigate the mystery, discover something terrible, try to survive with your sanity intact) remains one of the most compelling experiences in tabletop gaming.
What makes CoC special from a GM perspective is how differently it plays from fantasy RPGs. Your players aren't heroes getting stronger over time. They're professors, journalists, and private investigators who lose sanity points, acquire phobias, and occasionally die to things they can't fight. This fundamentally changes how players approach problems. When combat is almost always a losing proposition, players get creative in ways that surprise even veteran GMs.
Chaosium's published scenario library is the best in the industry. "Masks of Nyarlathotep" regularly appears on "best RPG campaign ever" lists. The shorter scenarios (collected in books like "Doors to Darkness" for beginners) work brilliantly as one-shots or convention games, which is partly why CoC maintains such strong convention presence.
The 7th edition rules streamlined the percentile system with pushed rolls and bonus/penalty dice, making the game more accessible without losing the tension that defines it.
Best For: Groups tired of combat-focused gameplay, horror fans, GMs who want a published-adventure ecosystem that rivals D&D's, one-shot and convention play
4. Star Wars RPG (Edge Studio)
Market Share: Largest licensed-IP TTRPG by sales System: Narrative dice (proprietary symbols instead of numbers)
The Star Wars RPG's continued popularity owes as much to its unique dice system as to the IP. Edge Studio (which took over from Fantasy Flight Games) publishes three compatible core books: Edge of the Empire (scoundrels and bounty hunters), Age of Rebellion (military campaigns), and Force and Destiny (Force users). Each supports a different Star Wars fantasy, and they mix freely at the same table.
The narrative dice are what make this system click. Instead of rolling a d20 and comparing to a target number, you roll pools of custom dice with symbols for success, failure, advantage, and threat. A roll can succeed with complications or fail with benefits. "You pick the lock, but the alarm triggers" is baked into the core resolution mechanic. For GMs, this creates natural story hooks on every single roll.
The downside: those proprietary dice cost money (about $15 for a set), and you can't substitute standard polyhedrals. Digital dice rollers in Roll20 and Foundry VTT help, but it's still a barrier for new groups.
Best For: Star Wars fans who want more than combat stats, GMs who love improvising from dice results, groups comfortable with narrative-first systems
5. Vampire: The Masquerade 5th Edition (World of Darkness)
Market Share: Dominant urban horror system, strong multimedia presence System: d10 dice pools, Hunger mechanic
Vampire: The Masquerade asks a question most TTRPGs don't: what are you willing to become? While most systems ask "what do you fight?", V5 asks you to reckon with what you're turning into. Players are vampires navigating political hierarchies, managing mortal relationships, and fighting the constant pull of the Beast within. The Hunger system (replacing the old blood pool) means every session carries the risk of losing control and doing something monstrous.
The 5th edition redesign divided longtime fans. Some loved the streamlined rules and the Hunger dice mechanic. Others missed the sprawling metaplot and mechanical options of earlier editions. Regardless of which camp you fall in, V5 brought a wave of new players into the World of Darkness, partly driven by video game tie-ins (Bloodlines 2) and actual play shows like LA by Night.
From a GM perspective, Vampire campaigns demand a different skill set than dungeon crawling. Session prep is less about maps and monster stats, more about NPC motivations and political faction dynamics. If you enjoy running intrigue-heavy games where combat is a failure state rather than the main event, Vampire rewards that approach.
Best For: Groups wanting mature themes and political intrigue, GMs who prefer social encounters over combat, players interested in character-driven horror
6. Starfinder (1e and 2e Playtest)
Market Share: Leading dedicated sci-fi TTRPG system System: d20-based, Pathfinder-derived with sci-fi modifications
Starfinder fills a gap that's surprisingly underserved: a crunchy, tactical sci-fi RPG with organized play support. The system blends Pathfinder's combat depth with space opera elements like starship combat, power armor, and interplanetary exploration.
2025 marked a transitional year for Starfinder. Paizo announced and began playtesting Starfinder 2e, built on the Pathfinder 2e engine, while continuing to support the original edition. This is similar to the PF1e-to-PF2e transition: a more modern action economy and tighter math, but requiring existing groups to decide whether to convert their campaigns. The 1e library of Adventure Paths and Society scenarios remains playable and extensive.
The starship combat subsystem is a love-it-or-hate-it feature. Each player takes a station role (captain, engineer, pilot, gunner, science officer) and the ship fight runs as a mini-game within the larger session. When it works, it feels like crewing a spaceship together. When it doesn't, one or two players end up bored while others do the interesting work. The 2e playtest appears to be addressing this feedback.
Best For: Pathfinder fans who want sci-fi, groups interested in starship crew gameplay, players who want organized play in a non-fantasy setting
7. Blades in the Dark
Market Share: Most influential indie system of the past decade System: 2d6 dice pools, fiction-first, "Forged in the Dark" framework
Blades in the Dark earns its spot through influence as much as direct play numbers. John Harper's design introduced the flashback mechanic -- instead of planning a heist in excruciating detail beforehand, you play the heist forward and retroactively declare "I actually planned for this" when complications arise. It solves one of the oldest problems in RPG design: how do you play competent criminals without turning every session into a three-hour planning meeting?
The system spawned the "Forged in the Dark" family of games, with dozens of published titles adapting its core framework to different genres. Scum and Villainy puts it in space. Band of Blades makes it a military campaign. Girl by Moonlight uses it for magical girl stories. The framework proved so flexible that it became a design movement, much like the Powered by the Apocalypse games before it.
For GMs, Blades is remarkably low-prep. The faction system, clock mechanics, and structured downtime phases mean the game generates its own complications. You don't need to plan what happens next because the crew's entanglements, heat level, and rival factions create pressure automatically. I've run Blades sessions with five minutes of prep and had them turn out better than D&D sessions I spent hours preparing.
Best For: GMs who hate extensive prep, groups that enjoy heist and crime fiction, players who want mechanical support for narrative play, designers studying innovative RPG frameworks
8. Warhammer 40,000: Wrath & Glory
Market Share: Primary Warhammer 40K TTRPG (Cubicle 7) System: d6 dice pool, tier-based character power levels
The 40K TTRPG space has a complicated history. The original Fantasy Flight Games line (Dark Heresy, Rogue Trader, Deathwatch, Black Crusade, Only War) went out of print when FFG's license expired. Cubicle 7's Wrath & Glory consolidated all those play styles into a single system with a tier structure: Tier 1 plays as ordinary Imperial citizens, Tier 3 as Space Marines, and so on.
Wrath & Glory's d6 dice pool system is faster to resolve than the old d100 percentile system, making it more accessible to players coming from other modern games. The Wrath and Ruin dice add narrative twists similar to Star Wars RPG's advantage/threat mechanic, so even failed rolls generate story momentum.
The 40K IP gives GMs an enormous setting to work with. Hive cities, forge worlds, space hulks, daemon-infested planets. Every session can feel different. The challenge is that 40K lore is decades deep and sometimes contradictory. New GMs can feel overwhelmed. The Wrath & Glory starter set helps by focusing on a single setting (the Gilead System) rather than throwing the entire galaxy at you.
Best For: Warhammer 40K fans, groups wanting grimdark sci-fi horror, GMs who enjoy running asymmetric parties (mixing Space Marines with human investigators)
9. Shadowrun (5e/6e)
Market Share: Cult classic with strong long-term retention System: d6 dice pool, cyberpunk-fantasy hybrid
Shadowrun occupies a weird and wonderful niche: cyberpunk heists in a world where magic returned in 2011, elves run megacorps, and your street samurai might be backed up by a shaman summoning spirits while a decker hacks the building's security grid from a van outside. No other system combines these elements, and that unique identity keeps players coming back despite the system's well-known rough edges.
Those rough edges are real. Shadowrun's rules are dense, especially around the Matrix (hacking) subsystem, which essentially runs as a separate game that can sideline non-decker players. The 6th edition attempted to simplify things with the Edge mechanic, but divided the community. Many groups still play 5th edition or heavily house-rule 6th.
The "pink mohawk vs. black trenchcoat" spectrum (loud, flashy runs versus methodical espionage) means two Shadowrun tables can look completely different. This flexibility is a strength for experienced GMs who want to tailor the tone to their group, but it means new GMs need to have a clear conversation with their players about expectations before session one.
Best For: Groups who love the cyberpunk-meets-fantasy concept and don't mind system complexity, experienced GMs comfortable with house-ruling, players who enjoy team-based heist scenarios
10. OSR Systems (Old School Essentials, Dungeon Crawl Classics, Cairn)
Market Share: Collectively significant, with individual titles in steady growth System: Varies, but generally d20-based with B/X D&D DNA
The Old School Renaissance is a movement, not a single game, and that makes it hard to rank. But taken together, OSR systems represent a meaningful share of the hobby -- and 2025 saw breakout successes like Dolmenwood (from Necrotic Gnome) proving that OSR games can compete with major publishers on production value.
The core appeal is simplicity. Old School Essentials condenses the 1981 Basic/Expert D&D rules into a clean, modern layout. Character creation takes five minutes. Combat resolves fast. The emphasis shifts from character builds to player skill: clever thinking, careful resource management, and knowing when to run away. A typical OSR session moves three to four times faster than an equivalent D&D 5e session because the rules get out of the way.
Dungeon Crawl Classics takes a different approach: it keeps the old-school lethality but cranks the chaos up with a "funnel" system where each player starts with three or four zero-level peasants, and whoever survives the first adventure becomes your character. The randomized magic system means no two wizards cast spells the same way. It's gloriously unpredictable.
Cairn and its derivatives (Liminal Horror, Runecairn) represent the newer wave of OSR-adjacent games that strip rules down even further while adding modern design ideas. Many are available free or pay-what-you-want on itch.io.
Best For: GMs who want minimal prep and fast-moving sessions, players seeking old-school lethality and resource management, groups interested in indie games with active creator communities
What Do These Rankings Actually Tell Us?
Looking across these ten systems, a few patterns stand out that aren't obvious from the list alone.
Why do some systems stay popular for decades while others fade?
Digital tool support is the clearest predictor. D&D has D&D Beyond. Pathfinder has Archives of Nethys and Foundry VTT modules. Call of Cthulhu has been on Roll20 since the platform launched. The Orr Report consistently shows that systems with strong VTT integration rank higher in active campaigns. With over 55% of US TTRPG players now using digital tools or virtual tabletops, a system that doesn't work well online is handicapping itself.
Organized play matters too. D&D's Adventurers League, Pathfinder Society, and Starfinder Society give players a consistent way to find games at conventions and local stores. That ongoing accessibility creates a pipeline of new players that systems without organized play programs struggle to match.
Is fantasy's dominance weakening?
Medieval fantasy still claims about 66% of the RPG market by most estimates. But look at this list: three of the top ten are explicitly non-fantasy (Call of Cthulhu, Star Wars, Shadowrun), and two more blend fantasy with other genres (Starfinder, Warhammer 40K). The indie scene is even more diverse, with systems like Triangle Agency and Mothership earning major awards for non-fantasy gameplay.
The trend isn't fantasy declining. It's everything else growing faster.
Where do indie systems fit?
Blades in the Dark and the OSR movement prove that market share doesn't tell the whole story. Blades' flashback mechanic has been adopted or adapted by dozens of subsequent games. OSR design principles (player skill over character builds, high lethality, fast play) influence even mainstream publishers. The indie scene functions as R&D for the entire hobby, testing ideas that eventually show up in bigger systems.
How Should You Choose Your Next System?
If you're a GM deciding what to run next, this ranking is a starting point, not a prescription. Here's what actually matters:
Match the genre to your group's interests. A group that loves sci-fi will have more fun with an imperfect sci-fi system than a polished fantasy one. Ask your players before you buy anything.
Consider your prep tolerance. D&D and Pathfinder reward investment in encounter design and world-building. Blades in the Dark and OSR systems let you run great sessions with minimal preparation. Be honest about how much time you have.
Try before you commit. Run a one-shot before launching a campaign. Most of these systems offer free quickstart rules or starter sets. You don't need to buy the full $60 rulebook to find out if the system clicks with your group.
Don't ignore what's already working. If your group is happy with your current system, you don't need to chase trends. Switching systems has a real cost in learning time and lost momentum. New systems are worth exploring when your current one actively frustrates you, not just because something shinier appeared.

What's Not on This List (But Worth Watching)
A top-10 list always leaves out strong contenders. Daggerheart (Critical Role's new system), Draw Steel (MCDM's tactical alternative), Mothership (sci-fi horror), and Mork Borg (art-forward OSR) all have passionate communities and growing player bases. Any of them could break into a revised top 10 in 2026.
The TTRPG hobby is healthier than it's ever been. More systems means more options, and more options means a better chance of finding the game that fits your table. That's worth celebrating, even if it makes "what should we play?" a harder question to answer.
Running campaigns across multiple systems? Keeping lore, NPCs, and session notes organized gets complicated fast. ScriptoriumGM works with any system -- upload your campaign documents, and our AI assistant helps you find what you need during prep or mid-session. No more digging through scattered notes trying to remember that NPC's name.
