I feel like I've been waiting for this game for years. I haven't been this engrossed in a game since I played Planescape: Torment.
The writing is extraordinary, the characters are vivid and all in all it's entertaining and challenging - especially if you play on one of the tougher settings. And the music is in a class of its own. I recommend anybody who enjoyed HoMM or King's Bounty to try out this game
