I have fond high school memories is of secretly installing Army Men on school computers. I'm not in high school anymore, thank God, but my love of toy soldiers can continue in...Toy Soldiers.
The upcoming Xbox Live Arcade game is a strategy game that probably has some action-y elements (based on how close the camera is to the firing units). I think it's interesting the backgrounds of the levels look so obviously "toy" while the movement and death animations look uncomfortably realistic.
Check out the screens for yourself:
