Pretty cool game. I do have to agree with everyone else about the game being repetitive and the siege scenes being slow. However, the sheer size of the game is pretty cool. Overall, I'd give this game a 4/5
If you are having trouble, you can increase the sensitivity by clicking options on the menu where you see the scores. It is the first option. With a sensitivity of 1 on hard, I could barely get 600. 2 was too sensitive for me. When I set it to 1.5, however, getting 700 was easy. Other than that, the game is very fun. 5/5
