Yeah that's what i was thinking, mine is more wishful thinking that they drop the obligatory romance for at least one of the girls in favor of a more interesting group dynamic.
Also, since we're talking about relationships, it would be cool if this time you're actually committed to a girl and the rest of the cast acknowledges it.
I just want the relationship mechanics to be more consistent across all the scenarios in the game. In P4 and P3, even if you get with a girl, they don't acknowledge it outside of the premade 'romantic' scenarios.
It would be extra work for many of the variables, but it would put a good spin on things i think.
