Maybe kinda sorta Conception II. It’s not well known, but I think it encompassed the art direction I would want to take.

The game is part dungeon crawling jrpg/dating sim. The only 3d parts in the game is dungeon exploration/combat and interacting with the love interests.
Honestly though, I hate the dungeon crawling genre and think that the settings and gameplay grow tiresome pretty quickly.
If I had the choice, id make the game open world tokyo, with a combat system similar to the witcher 3. The dating sim elements would play an important roll in determining the story arc you would go down and also influence special stat bonus’s that apply when you are partying with this character…which is all pretty ambitious. This was my original idea, but honestly…this sounds like a game that a triple A publisher would have to produce. Im sure no indie team would even want to attempt something like this. Q.Q
Which is why I think a visual novel/Dating sim would be a cheaper alternative, that would provide a similar impact.
