This is like THE quintessential N64 adventure game. I miss those carefree days of yore when Rare would make games like this (DK64, Conker). Those were happier times! And speaking of happy, that's exactly what Banjo-Kazooie makes me feel. Just a great, fun, splendid all-around game with so many moves and collectibles and levels to explore that playing it once isn't enough. Also, Stop N' Swop? BRILLIANT.
