Found a copy of this for $5 yesterday at a Resale Shop. I couldn't get Daemion off it for a second to play ExciteBots.
Needless to say, he loves it.
I've noticed that a lot of people don't know that the Wii is backwards compatible with Gamecube games. They are cheap and sometimes just as good as any Wii game. So if your looking for a cheap game for your kid or yourself to play on the Wii, look no further than your local GameStore... or even better, Flea Markets, GoodWill and Pawn/Resale Shops.. They usually don't check prices of the games online, so sometimes you can get some great first party Nintendo games for just a few bucks!
