Typical indie H dev thought process: I like skyrim and fallout, and I like porn. I know! I'll make a massive open world sex sim unlike anything made before! Look there are all these nice store assets to get me started!
You do realize those games were made by one of the largest of the giant AAA dev teams with tens of millions of dollars and it still took them years to push out a half broken product, right? Like, not knocking your efforts, but choosing the right level of ambition is THE most important starting point of any indie game.
