i personally thought about combining Touhou with SMT/Persona series.
Lotta character with it's own characteristics, expendable world, etc.
also Reimu can actually summon Gods which kinda similar.
Yukari got the similar role as Igor.
also i already set in mind who the main antagonist is.
what's left is the teammates though, i can use snae... but the others... eh???
i havent think much about it.
actually IF i can code, i probably makin it right now. but yeah.... i cant...
