I want a framework to build something with my group. My love of PbTA comes from genre simulation. That can be looser like Monsterhearts or more structured like the watch it’s not like City of Mists.
I’d go for direct franchise games next - Doctor Who is ok (but really a RTD emulator), Star Wars is near but give me Star Wars World every time. Star Trek and 2D20 is a form of pergatory.
That is not to say that a detailed setting like CoM, Blue Rose or ever Forgotten Realms are not fun - but the level of investment is higher - for the GM and the Players. I am sometimes in awe on that level of investment they put into games but not for me, at least not any more.
