Hear me out.
RPG
With strong social and interaction engine, not just a dialogue tree that repeats over and over. And please, don't turn allies into non-entities/non-characters once they are recruited. Ideally allies would still be interacted with and they would keep their own distinct own goals and storylines.
Generous virtual paper doll and dress up elements. I don't wanna wait half the gameplay before being able to engage
Important, let me play the main character as fully non-action snd support. Should be able to never make an attack and never blast. And make it easy to pull off. (Not in difficulty but in accessibility. Be generous with recruitable party mates that can carry one's weight. If I have to seriously own a weapon and spent tens of levels as a killing machine before being allowed to play a weak and vulnerable main character it isn't what I'm looking for. Ideally some kind of noncombat rogue, pet master, purely utility mage, or even lilly white mage.
Focus on exploration, interaction, puzzle solving, even intrigue. Combat is unavoidable to have, but please don't have scripted death or life combats within the first ten minutes (I'm looking at you Birthright). I don't want an action prologue. The more optional combat is, the better.
Btw, prefer turn based combat, but real time is fine provided we aren't into hack and slash or full on action RPG territory.
As for graphics, I'm fond of cell-shaded with anime aesthetics. Not an strict requirement though.
I'm fine with romancing options, but better if they are not mandatory and you can choose your options. Please no harem dynamics, love triangle is fine, maybe a three point star, but no more.
And well, please don't make it into a waifu factory. Have diverse companions, don't make everybody just "generic anime girl that embodies someone's fetish number n".
