4 player battle arena was amazing, I had one friend who was annoyingly good with the tank and would routinely annihilate us with it, to the point where it was briefly banned in SF64 multiplayer in our group. Same friend showed me how to save Falco in the first mission, effectively unlocking the other half of the game for me. Fun, incredibly quotable campaign. I don't have the same sentimental attachment to it that I do for, say, the Legend of Zelda games, but I do have a lot of fun memories associated with it.
