I liked the first Zelda for Nintendo 64. It was pretty tight. It was also a pretty damn big game in my opinion. I foundit mysterous also, going through the desert following that ghost, going through that temple where at the end you fight Bongo,those hands... (it was a freaky yet totally kick ass game) Plus I liked riding and jumping with Epona... lol
Conker's Bad Fur Day, Ocarina of Time, and Banjo Kazooie/Tooie. Conker was just too damn funny to not love, Ocarina was just AMAZING in every category, and the Banjo games had some of the best level design, character design (for Rare standards) and music of any N64 game.
Zelda forsure, good old Golden Eye, and Super Smash Bros. Zelda because it is so indepth, goldeneye because its fun shooting things, yet still think, and SSB because its the best multiplayer game alive. (maybe other that SSB Melee) Oh yeah and Gauntlet Legends, its fun mindless destuction.
