The Ghost of RubangB on 19 June 2008
Welcome to the Chartz duder.
They're both great games, but to be honest, MKWii's online will make it last forever, and it's fun to keep going back to unlock more vehicles and characters, and there's online tournaments with new stages.
MP3 has the most amazing controls ever, but has no replay value.
I'd buy MKWii new and find a used copy of MP3.
