Nintendo launched their Club Nintendo service in North America yesterday. It is basically a frequent shopper program for Nintendo products. You buy Wii systems or DS games or anything from Nintendo and you can get coins. You can also fill out surveys and get coins too. Accumulate enough coins and you get rewards. Some of the rewards are pictured below.
Most of these rewards are not sold in stores and will only be available to Club Nintendo users so they will probably be fairly rare. Pokemon Box was only sold at the Nintendo World store and now its one of the more rare and expensive Gamecube games. The Game and Watch Collection for Nintendo DS (600 coins) will probably become a collectors item too (and it could actually be fun while Pokemon Box is not).
Right now the site is pretty buggy. I tried to change my old My Nintendo account into a Club Nintendo account and the website ran very slow. When it finally went through it I would get kicked out of the site and have to log in again whenever I clicked a link. Hopefully Nintendo works out these bugs soon and we can all get some more Nintendo games and collectors items.
