I've played a ton of the japan demo and if you don't like monster hunter this game IS for you. All the combat is magic based and not monster hunter animation priority type melee combat. This is the monster hunter game for people that don't like monster hunter.
Soul sacrifice has a full on story based single player game. If you choose to save the bosses instead of sacrificeing them, their human forms become AI teammates that actually help alot in battle. The story might as well me an assassin's creed game story. Merlin has taken over the world and turned it into a hellish place, where humans are kept in cages only to be eaten by merlin for their magic. Your reliveing the memories of famous mages through a talking book in your cage. The more memories you relive the more magic power you get in the real world. At the end of the game I assume you bust out of your cage and go fight merlin. To call SS a monster hunter clone is a huge disservice to it. it has a lock-on button, so right already waaay better than monster hunter.
