What other vectors? Are you seriously telling me you are playing an adult game not for adult content but for gameplay when you can play any other decent game from any other genre?
You want rpg? Play witcher, gta, fallout, elder scrolls, mass effect etc.
You want fps? Play cs, cod, battlefield etc.
You want hack&slash or beat-em up? Play dmc, bayonetta, mgr etc.
You want survival? Play ark, rust, the forest, raft etc.
You want porn games? Play porn games.
Don't expect gameplay elements from any other genres in porn games, it is unrealistic af and if developers go that route they'll inevitably ruin their game.
So you want erotic and adult elements rather than actual thing AND you want gameplay? You are in the wrong place. Just go play any game with nudity in it like Witcher 3.
