Absolutely unoriginal, but Fallout New Vegas. Maybe more original take, but I prefer raw-dogging it too. I haven't found a mod yet that doesn't feel like it takes away from the experience.
Seriously, what this guy said. Four Elements trainer is probably the top tier of all nsfw games in general. Also shoutout to their side game 18titans, not as fleshed out but also damn good.
If you're alright with fandom games, I know there's optional side content for this in Four Element Trainer on the Slave route. I don't know if you want hard domination like that though, or would prefer OC stuff, but it's the only one that springs to mind.
Most of my reccomendations are either in the games plus category or require good translation software... it seems like it's a fairly narrow field unfortunately.
Best advice for new players? Just turn on cheats. Right out of the gate. You're realistically not gonna miss anything as the segments to increase your stats aren't tied to any sort of story the events are locked behind each other, so you'll still see all the content, and not have to go through...
This game is absolutely incredible, even if progress is a little wonky. Could really use a good walkthrough for the later segments, or especially a walkthrough mod so you don't miss content.
The ending felt a little anti-climactic and I'm not sure if that's because of poor decision making or not. Can anyone confirm multiple endings for this game?
