if didn't play the old dungeon master or eye of the beholder games and didn't like its silly gameplay mechanics, then the game is not for you. if like it, then its a great dungeon crawl. no bugs, it start and runs super fast on old trusty MacBook Air. its not too long, so normal people can finished it in 25 h, its not an ever-grinding 150h stretched hell.
Directors cut is great ! no bugs so far, diffculty settings are flexible from easy to ultra hard to 80 style or mixed. it has classic grid based navigation option for same retro flair. ok, the art director totally mess-up with dwarf or elven design but still its great CRPG !
