I got a wii few days ago. I just played wii sports, my gf keeps complaining how her arm is so sore. she wants to play oldschool games or maybe gamecube games. I know that vc controller wont let you play gc games. If I do not play that, which is a better choice? How compatible is GC controller with VC games? I saw 2 GC controllers on ebay going for less than 20 including shipping while VC controllers are 20 + tax retail each.
