To be really honest with you, I rreally think this game is overrated. The graphics are very nice, and it's very well designed, but the game concept is just too simple and repetitive. Rated it 3, though.
Seriously, PLEASE do something about the bricks. They are the easiest to earn and the ones that take less to do something.
Whenever you're almost winning, your opponent just use a Fort card and rebuilds the entire castle. PLEASE FIX THE EASY BRICK BUILDING!
