Surprisingly good. Deep and variable game mechanics. Active characters with good behavior algorithms. No, I'm serious here, it's really a bunch of non-playable characters acts and interacts with each other in this game. They cooperate, share information, help and fight each other, I saw it by my eyes and wish you to try this game too. And a little nice bonus: all texts the game have sense so you don't have to kill you mouse button. No actually porn content noted though there are sexual intercourse and some erotic art in game and... the game itself. It's actually a game here. Ah, yes, and you are dungeon master.
