It seems to me you just don't like 3D or most of the 2D games around here.
Otherwise, bear in mind that the porn industry as it is is mostly indie, with most "studios" being a one man army or 2-3 people, either way, what are the chances of that few people coming together and doing a game in a years long effort potentially with very low pay rate? I hate to be that person, but if the best you can do is find a game you like and give them your money, there are quite a few of the top patreon moving for bigger teams and semi professional set ups with their increased pay, and it's the best way to attract better artists and writers.
