That's insane MikeB, as amazing as Mario 64 was, it became one of my lesser played N64 titles for sure. I spent most my time on Perfect Dark, GoldenEye, Staw Wars Pod Racer (lol, I just loved it), LoZ:Majora's Mask, WcW vs NWO Revenge, and for some reason, Automobili Lamborghini. Donkey Kong 64 was great too.
And how could I have forgotten, Mario Tennis 64, that was such a freakin' amazing game, me and my brother could play it for hours. OMG and of course Super Smash Brothers, another game that could be played for.. ever.
Oh yea and Conker's Bad Fur day was just hilarious, I never got into Banjo Kazooie though. OH and Jet Force Gemini was such a great game, it deserved more success than it got in my opinion. Carmageddon 64 I loved aswell, I've always been a fan of that series though, and CastleVania 64 was amazing, creeped me out a bit too. I really liked Extreme G2 (couldn't find the first), I loved going at the ridiculous speeds and blowing the crap out of the other bikes. Oh yea and I was into the Pokemon craze at the time so I got Pokemon Stadium which was fun. Argh and how could I forget Rayman 2:TGE, that's just an awesome game.
Games that I couldn't get but wish I had are Kirby64. Mario Kart64, Clay Fighter 63 1/3, Rogue Squadron, Turok 1/2, Vigilante 8, Wave Race 64., and Yoshi's Story.
Oh and just remembered Rampage: Universal Tour. That game got amazingly terrible reviews, but I loved it. Me and my bro could just play it ages, it had such repetitive gameplay but it was so fun lol. OMFG and Snowboard Kids!!! That was such a funny game, I preferred it to games like 1080 for some reason. Oh yea, StarFox 64, what a game, although it took me months to get the balls to go down the difficult route (when I found out that was the good ending I was kicking myself). And Worms Armeggedon.
Basically I'm stunned you guys found yourself stuck finding N64 games, absolutely stunned.
