It's a great corruption game. That said, it's not perfect. I recommend a cheat mode that can undo the slave transformation, after you finish the story, as it blocks a lot of individual content with the characters Oh and more prego would have made it better :)
If it's a game I put a lot of time into I might get frustrated at the thought of having to replay old content, but in general it depends on how grindy the game is.
