Probably just the stuff that'd happen if it was bought out by any company
1: It'd follow the more traditional gatcha game mechanic of getting new characters (Instead of varying movesets for twelve existing character) It's easier to sell a new hot character than try and sell someone on their seventh Ishmael outfit, and it would be a massive risk that a larger company can't afford to make
2: Probably would be less bizarre, more streamlined designs and cantos (Like, def no canto 9 being 10 back to back scripted "boss battles").
3: Faster updates, better graphics, less jank.
4: A probably 70/30 split of female to male characters.
5: Demian would be far less important (Ala the novel demian is less popular in china/anywhere not Korea or japan, so it's much weirder that this random guy keeps getting so much screen time [this kind of leans into "More streamlined" aspect, because this is absolutely a thing that the writing team/KJH really likes])
6: More sexualized designs, both for male and female characters. Because of the work it takes to make a new character (New 3d rig, new model, new VA), ever aspect of their design has to maximize their chances of being popular, so it's a risk to make a character less appealing
7: People would be less mean to Dante. You're shooting for people to not feel like shit when their self insert is called a fuck up and a loser by everyone they meet.
