N64 with 4 joypads. Nothing has ever, EVER come close to the epic Goldeneye (and later Perfect Dark) sessions that I had in the late 90s. Carnage, brutality, intimidation, high-pressure multiplayer action, non-participants enthralled by the action, winner stays on, it was the essence of gaming, the crucible.

The 64 had so many great games. Mario 64, Mario Kart, the zeldas, banjo kazooie, Rogue Squadron - even some of the less heralded gems like Blast Corps & Wave Race just had that charm, even the WCW wrestling games brought something. I loved my Amiga but the N64 was the pinnacle for me.
