My little brother and I love this game! I adore the simple controls and yet this game has the potential to harvest an epic strategic war. One thing that makes this game quite unique is the mechanics of attaining cash. Waiting for the timer to hit zero and the differential in the rate of money per turn is very different from the typical war game.
Why I put myself through such torture that inevitably turns into rage is the pure desire of achievement. It is these types of games (which make me feel somewhat masochistic) that are so deliciously rewarding at the end of the countless deaths.
I must say, GREAT GAME! It's also very challenging, which I like :) A practice mode where one could practice just parts of a song would be quite the help.
