Anyone do puzzlers? I used to play the shit out of "The NEW Tetris" on N64 with my buddies. They all fucking sucked at it. Haha. We played it all the time and they'd get pissed because my girlfriend and I would still be going strong for like 20 minutes after they died.
On the other hand, they would kick my ass without missing a beat in smash brothers pretty much every time. N64 was a sort of golden era for multiplayer-in-the-same-room since it was the first 4-player-out-of-the-box console that gained mass popularity. Mario Kart anyone? Don't worry, the computer will guarantee we all win! LOL.
Also, there's this awesome old PSX game called Devil Dice, easily one of the most addictive puzzler type games I've ever played.
