To be fair, The Last Sovereign pulls off philosophical discussions to amazing effect. It honestly plays less like a porn game than like an RPG with sex as an underlying theme.
I can imagine. I haven't played the last sovereign, but Sierra lee is a great writer, that's for sure. Pretty much, most of the big japanese hentai novels exposing important subjects that you can think about. They are like regular works, but only with the climax of a romantic relationship in the form of sex between lovers (Not necessary only between lovers, but you got my idea), for example.
So, yeah, I was just ironize. But unfortunately this game, not trying to give you straight answers. The narrative is jagged, and the main character is in a state of delirium.
I don't want to badmouth the game too much, maybe I just didn't understand it (I mean, it happens, right?), but personally I didn't understand what it was about at all.
And there were no guro or any disturbing fetishes so far, if anyone wondering about it.
