Heck yes I do. I still have my old N64 and a bunch of games. I don't really buy N64 games on the Virtual Console though, since I have an N64, but I did buy the DS version of Super Mario 64 even though I have the original game, because I feel that they added enough stuff to make it worth a buy.
I do Mario Kart 64 is still one of the best racing games EVER! Both Zelda's are classic's, Mario 64 has some great levels, Paper Mario is a great RPG and too many other great games make it the best system YET to be made.
