This list includes every published game I have played or GM’d. It does not include games in playtest, ashcans, or homebrew rules. Games using the same core rules, but still fundamentally different, or different editions of the same game are grouped together. I am certain that I have left off games, such as ones that were one-shots, or very short games during college.

That’s 83 games if you count different editions of the same game as being different games, which can be argued either way for many of the items on the list. It’s 60 different rules systems, give or take, depending on whether you count things like 7th Sea and L5R as different systems, or the different incarnations of White Wolf’s die pool system through different genres.
