If you like games that feature non-con/r*pe then this game is a must play. Even if you don't, you can skip seeing the content without changing the outcome of the game (in most situations as far as I've seen).

The combat is simple and if you lose you just head back to your character's room. It's more like a check to make sure you've done enough in the rest of the game.

The H scenes are hot (especially if you like the previously mentioned type of content) however there are consensual encounters too.

Look, it's just a really well made game that explores themes of fate vs free will and how much evil can you do in the name of "the greater good" and still consider yourself a decent person.
