Game was brilliant. One of the few arcadey type games I actually played more than the original Starfox. SF64 had some of the best stages in that type of game EVER. Man, finally figuring out how to truly complete the Forever Train was one of my greatest moments in gaming. Purposefully losing in (Katina, was it?) and getting the Independence Day-like destruction of the base was just... awesome.
Scoring the Gold Medals on all of the stages, unlocking Expert mode, and getting all the golds again. Whew... Good times.
