Well, Scorched Earth was pretty much the first PC game I ever played, and boy did I love it. Buying weapons, nuking the crap out of other tanks, it was just plain fun (go MIRV!).
So I was checking out GameTrailers.com this morning, and guess what I found? Apparently, there is a Scorched Earth-type game on XBLA!
Check out the gameplay: http://www.gametrailers.com/player/45823.html
Is this awesome or what? My only peeve is that the tanks can move I need to try it. It'd be the first Live Arcade game I buy if I like it.
