So there are ingame costumes you can get beyond the DLC ones? If so that is good to hear.
Yes there are plenty of costumes not exclusive to DLC that you can choose to use if you hate eyepatch Kiria and Kentauros Tsubasa.
I really liked p4 but I'm not a big fan of all the jpop idol garbo that seems to be a big thing in this game, is it really in your face about it? Also whats the consensus on the story, is it better than offensively bad?
It is a game about idols and the idol industry. I'm sure it is in your face and then some.
The story is a character focused one that is more of a maturation and coming of age that ends up as a mostly positive message and feeling by the end with some dark elements that help lead up and build the character development.
The entertainment motif is more of a vehicle to drive character interactions and growth as that is a lot of the focus and where the game excels most.
The story is no where near offensively bad like say Fire Emblem Fates was.
I mean there isn't any other game that has Quentin Tarantino and Marty Friedman from MEGADETH and Hatsune Miku parodies all in one game so I'm pretty sure even despite the music, there are a lot of references and interactions regarding other parts of the entertainment industry in it.
There are like only 2 characters that want to be an idol, the rest want to be actors, television hosts, models, singers/vocalists, stunt artists, and more.
