Games where you take a quiz at the begining and that defines your build, class and other kind of stuff.
I love that shit, man. It's like horoscope for nerds without being gay like those personality types things.
It also makes every playthrough mostly unique and personalized to some level.
It's just something i really really like.
Surprisingly, i know few games that do this:
>Pokemon Mystery Dungeon
>Growlanser and Langrisser series
>Jojo 7th Stand User
I'm sure there are more but these are the ones i've tried.
