For only 100 Coins, Club Nintendo members can now pick up Dr. Mario Online Rx for the WiiWare service. This reward will be available until October 14, 2012.
This is one I’ve been wanting, but always passed for something else. Unfortunately, I’ll have to pass once more as I don’t have enough coins at the moment. However, if you do, this is a chance to get (from what I hear) a pretty good game.
