I really don't believe anyone wants Less content, but they just don't want to wait. Game is big and enjoyable BECAUSE dev. spent time to make that content; and they want to continue to make content because their vision scope is beyond what's currently visible. If you started the game when it didn't have anything, you'd just complain that there's No content.
There's 2 issues here:
1. What are you expecting from the dev. here? Once he's finished with the game, that he's going to make another game that's just going to be similar to this with a different premise. Where's the fun in that? It's better to add more content to the already existing game that you are already familiar with.
2. Are you here for porn, or are you here for story? Why do you want less porn so you can be "finished" with the game so you can move on...? If you are bored with the game, then just stop playing it. You achieve the same result. I don't see the point of stopping content so the game can be "finished" so you can move on and not play it anymore?
