With a new month comes a new selection of downloadable games for which you can exchange your Club Nintendo Coins. The new lineup is half as varied as those of previous months, offering only one DSiWare download and one Wii Virtual Console game.
For 150 Coins each, you can choose Art Academy: First Semester for DSiWare (but only available on 3DS through this offer) or Mario Party 2 for Wii. If you get that one, use the money you saved by buying it with Club Nintendo money to buy some extra controllers, either for friends or to replace the ones ruined byMario Party.
For fans of physical, tangible goods, there's also this new 3DS card case. It holds 18 games and includes four "double-sided card covers." And it looks really nice.
