I think a monthly update just to know what the team has progressed is good but i dont like playing a game on quotas i'll forget everything and i don't want to play the game again until the updated content.
Had to go with Rpgs but i play anything if the game's good no genre is gonna make me not play it, i hate platformers but Celeste and Pizza Tower are godly, so much fun.
Devs of porn games should focus on one aspect of the game, either you have a solid gameplay or lock on the story and writing, they don't have unlimited resources to waste.
I have seen games put pointless mechanics that adds nothing to the aside for making you lose time, like Prince of Suburbia...
