A great game, and I'm talking about the actual game here. There's sex, but there's an actual game with actual mechanics here. If you wanted to just not engage with the sexual mechanics, it's still a solid RPG.
That said, the Corruption side of things is *actual* corruption. It's not just "oh, now I can enjoy kinky sex!" corruption, but actual twisting of the protagonist's soul until she goes from being a good hearted hero to being a fascist tyrant. I found the corruption truly uncomfortable. The game gives you good reasons to struggle to keep yourself pure despite the challenges it provides.
This game truly deserves 5 stars.
