I remember the first time I saw this game... What a beautiful memory.  Even though the Nintendo 64 turned out to kinda bust, it was my transition from 2d to 3d games.  My first experiences with 3d were with Mario 64.  I first played Nintendo 64 at a friend's house, and Wave Race 64 was one of the first games I played.  My jaw was hanging for about a half hour.  The first thing I saw was Dolphin Park - swimming dolphins, fish, "splashy" sounding music, backflips, barrel rolls, and BEAUTIFUL water.  It was too much!  What a surreal experience!  After I got back up from fainting, my friend and I played this game for HOURS and HOURS and HOURS and HOURS.  We would go to Southern Island and tried to find what we could ramp over, go under, and crash into.  It sounds pathetic, but I've had some of the best times of my life playing Wave Race 64 with friends.
