I didn't learn Fate well enough to know how it would work with long-term PBP. (I was kind of watching this one to see how a game of Modiphius's Conan might work. It has a similar system of earning, spending and sharing meta points). I think a Fate game maybe could work with a small group of dedicated players. The way my Bushido game (very crunchy 1980s rules) has gone on for two years next month-- with only a GM and two players.

Thanks much, Leitz!
