Against your disdain for people that already own the gc versions
I owned RE:4 gc edition, played through it many times
RE:4 wii edition came out, so i bought it and gave my friend the gc version
Later, when I bought a couple more gc games, i ran out of memory card space, and this friend gave me a couple he wasn't using.
I'm not sure if I'll buy the pikmins, but I never owned Metroid prime, so shall deffinately get that. I have prime 2, but i might get that and give the gc version away
