Advance Wars (2001)

Just because this battle fits in the palm of your hand doesn't mean the stakes are small. On the contrary, this all-or-nothing fight will have you accessing guns, grenades, launchers, and weaponry of all sorts. Players assume command of an army that's out to reclaim a world that's been broken up by warring factions. The battle map is essentially a grid, and moving units is like moving chess pieces on a board -- each of the units can move a specific amount of spaces within this grid, and can only attack at a certain distance from specific enemies. Advance Wars features more than 115 maps, a map editor, head-to-head play via link cable, and an easy-to-understand tutorial mode for beginners.
