So I have just bought Twilight Princess. I was in the charity shop on my work break and there, on the DVD and game shelf there it stood - for the Gamecube! Now I remember hearing something about how this version is rare but I'm not too sure now because I found it in a charity shop for £3. So that leads me to two questions. 1 - Is the Gamecube version rare at all? And 2 - How long will it take to complete?
