Not really a fan of this type of games, but i must say that this one is catchy.
Good graphics and controls that are easy to master, being this last part not easy to find in this type of games.
The story, although i haven't finished yet, is very good.
One thing that i'm really looking forward is the multiplayer cause this must be an awesome game to play against other players, but i haven't tried out yet cause of region problems.
About the grade, i have to say that it doesn't get higher just for the pure fact that in general this type of strategy games doesn't appeal me, but this was a nice change.
To sum up, worth the $. :)
ps- if you love chess than this game is definetly for you. It makes you think and plan every move you make cause if not, you'll be the surprised one.
