Obsidian Portal, an online campaign management tool for RPGs, shares stats on the number of campaigns run in its system. I’ve created a Google Sheet with this data.
This represents the 129,098 campaigns created over the lifetime of the software (12 years, as it was created in 2007). As a result, you’ll see Pathfinder in second place at 18% of campaigns, due to its historic strength: it is doubtful that 18% of campaigns played today are in Pathfinder, given the loss of players to D&D 5e and the release of Pathfinder Second Edition.
D&D, across its editions, represents 47% of these Obsidian campaigns.
The Top 10 systems that aren’t D&D are:
- Pathfinder RPG (17.66%)
- Savage Worlds (2.40%)
- Shadowrun (1.94%)
- Fate RPG (1.88%)
- World of Darkness (1.83%)
- Star Wars: Edge of the Empire (1.80%)
- Call of Cthulhu (0.98%)
- Vampire: The Masquerade (0.85%)
- Mutants and Masterminds (0.72%)
- GURPS 4th Edition (0.70%) (1.25% if you add in earlier GURPS editions)
The full Google Sheet is here.
