Advance Wars 2, in my opinion, is the BEST game for the Game Boy Advance. When I showed my friends this game they both bought it and a Game Boy Player just so that they could play it on their TV. It is a strategy game similar to PC games like WarCraft or Age of Empires except for a few things. For one, it is turn-based so you move your units to attack other units and/or deploy new units, then choose to end your turn. It is also different in the way that you don't build any buildings. Instead you capture neutral and enemy cities, bases, airports, and shipyards with infantry units. The more buildings you have the more money you get each turn. The reason that Advance Wars 2 is better than the first one is that it has all the old levels plus more. It also has more than double the characters. If you get tired of the near hundred levels you can always make your own in the level editor. So if you want a game that is really fun and has awsome replay value, this game is for you.
