The folks behind Roll20, The Orr Group, have published their annual stats for usage. Roll20 is one of the most popular ways to play pen and paper roleplaying games over the internet with over 4 million regular users, so while the report isn’t a comprehensive look at the industry, it’s an interesting snapshot of a large part of the community.
The summary is that an overwhelming majority of the Roll20 players party up in Dungeons & Dragons 5th Edition games. In both campaign and account participation quantity, it’s over 50% to D&D5E, with everyone else making up the rest. Pathfinder, the system that for many years captured the hearts of older school D&D players, gets less than 10% in either category. Most surprisingly, Call of Cthulhu (any edition) tracked high on both measurements, even surpassing Pathfinder in the number of campaigns played. Iä! Iä! Cthulhu fhtagn!
