Advance Wars is a turn based strategy game where yellow comet (japan), green earth (germany), blue moon (russia) and orange star (the states) are pitted against each other until they join forces and defeat a fourth, hi tech nation, the black hole (which reminds me of nazi germany due to dress codes and the evil intentions)
You pick a commanding officer from a list of lovely designed weirdos who posses unique special powers, build tanks, infantry, planes, ships and the usual war machine lot, capture cities, bases, blow enemy stuff and all.
