Fiasco is kind of tough because there's no real conflict resolution like in more traditional RPGs. Even in something with complex dice rolls like Genesys, there's an outcome decided and you can use that to guide actions and outcomes. With Fiasco, it really just is improv scenes and you play up your relationships and goals.

I totally agree it can be fun with the right group, but the right group is either very open minded and comfortable with each other, or decent or better improv players.
