the wii is actually better than the gamecube.
I think metroid prime being the best game on either system is what made me hold on to that for so long, but other than metroid going to hell with other m and brawl doing about as badly to that franchise..SS is better than either GC zelda easily, galaxies are better than sunshine, xenoblade and TLS bring a revival of JRPGs, and it's the best console for platformers since the SNES
still missing star fox and f-zero though :/ not that the GC star foxes were great but at least they tried!
