As a Project Sekai fan, the closest thing I can get to "personality sorting" in the game would be Sekai orientation—that is, a private world born from a paroxysm of intense emotions. I don't think it suits the prompt very well however, seeing it's inapplicable to real life (a pity, really, 'cause it sounds freaking awesome). Another one I quite like is Genshin Impact's visions, which reflect the vision bearer's goals or ideals (a good explanation can be found here), though it isn't really something explicitly discussed in Genshin (at least to my knowledge, I haven't played it in ages) and is more a theory than anything tangible... I dunno!
