It's Advance Wars on an HD screen. Take it or leave it.
For those unaware of the DS strategy game, Advance Wars has you out on a grid making strategic moves in order to overtake your opponents bases. Building up various units, such as air and ground, couple the strategy. The combat has a rock-paper-scissors feel to it, since some units are better at taking out certain units than others.
That's pretty much all that can be said: You like Advance Wars and have a 360? You probably purchased this already. If you still need a deciding factor, this game isn't Band of Bugs. So, hopefully that will help you out.
