Just a heads up. On April 2nd, 2012, Gamestop will no longer be accepting Gamecube games/systems for trade in. So if you are a collector or want to get your hands on some of the really good games Gamecube had to offer (yes, there are some >_>) best to start looking around.
I already got my list together and got things like Wind Waker, Mario Sunshine, Metal Gear Solid, etc.
