I see it there. It would be cool if someone made a more modern flowchart.
Okay, what do we add?
Needs some Dogs in the Vineyard for Western fun.
Their future post-apocalyptic is GURPS Fallout. Need to add Gamma World and Apocalypse World, which others are we missing?
Which brings up all the other various Powered by the Apocalypse games. Does something like Monsterhearts require a "Teen Supernatural Romance" category? Or perhaps just Romance and include Blue Rose?
Blades in the Dark. Victorian Crime as a subset of fantasy.
Near-present we can add crime to the breakout and add Leverage.
Huh, it's got ICONS on it, but not Marvel Heroic Roleplay? Is ICONS a lot older than I thought?
