Club Nintendo members were in for a surprise treat last month when Nintendo started finally releasing downloadable games in exchange for Coins; previously the rewards had been mostly screensavers and posters.
They're keeping it going this month with Art Academy: First Semester for DSi Ware on the 3DS and Mario Party 2, the N64 original, for the Wii's virtual console. Both games cost 150 coins, so you should only have to register 3-5 games and take a few surveys to get enough.
To put the Coins in perspective, I combed through my personal collection of Wii, DS and 3DS games last month so I could get Majora's Mask, and ended up with over 1000 coins from all my unregistered games. Piece of cake! Do you have enough lying around to get some more free games from Nintendo? Let us know in the comments or on Twitter.
