Back in the day one of my favorite games was Advance Wars. It was a cool little military RTS game on the Gameboy Advance. However, the game never made it to any Playstation or X-box (I think it got ported to Gamecube and DS).
Now, a few months ago I ran across this iPhone/Android game called Great Big War Game; it is basically modern version of Advance Wars.
Great Big War Game just went free on the iPhone by the way (used to be $2.99), and I believe the Android version is 99 cents. If you have some time, give the game a try.
