Yeah I'm real glad I still have a n64. Perfect Dark co-op is so much fun with friends, and ahead of its time, i think. You can get emulators/re-releases of all the classic games, but it's still super fun playing 1080 or Wave Race with a crew of people, with those big clunky controllers.
Just grabbed a copy of this too, which is super fun/nostalgic. I used to always rent it first day of summer break for like 3 years straight.
I still got a ps2 tucked away, with like Ico, Final Fantasy vii & viii, metal gear solid, and like Tekken 3.
Still wishin I held on to the Genesis though.
