It looks interesting, but I'm concerned about the replayability. Also, the situation with the castles, where only creatures of one level are available, and the type of these castles must be chosen before the start of the game, is a bit strange. Furthermore, judging by the comments, AI players without an alliance can fight and kill the quest heroes :(
P.S. Did you know that a cyclops under hypnosis can break its own wall? :)
