in fact, we'd love to have a community driven development so we build exactly what people like
I don't post often but, This is a TERRIBLE idea.
These forum don't agree on anything, you would need to build several different versions of the game, and you would probably still get hate from ppl. For starters you would need to build an NTR, Harem, Solo, Lesbian, Gay, Trans, all seperate versions, and an all in one version for the degenerates. Oh shit I forgot furry, probably more, damn also forgot there's a couple people that post in most game forums lately asking for small dick main characters. You would also need to build a grindy and non grindy version for each of those versions. And these are some examples of what you will get when you ask random ppl to post what they want.
And if past devs are anything to go by, asking the public what they want is stupid, and you cant move things forward with the game development because ppl want you to make things, usually character specific, and those things are not what makes sense for moving story or plot forward. And then creators get tired and burnt out from never moving forward and abandon their games. I mean there are other reasons too, but that's just an example.
I dont know if you are planning any story or plot but if that is the case, I personaly wouid not ask for suggestions from forum ppl. You could ask for feed back, but even with that some ppl here can get super toxic, so you best have thick skin and not take shit personally. It's why so many devs don't come here anymore, they get butt hurt and are gone.
In the end you do whatever you want to do, but that's my thoughts on what you said.
Good luck with the game.
