Yeah, I love DK64, I still revisit it for another 101% run every few years! I prefer Banjo-Kazooie though, DK64's collecting just seems a lot more messier and can get pretty grindy at times, especially the amount of backtracking across the level needed with the different Kongs. Apart from that, I'd say they're both on par with each other (except for DK64's lack of dialogue, only minor), but on a personal level Banjo-Kazooie also wins for me, I've always loved it that little bit more so I guess I ended up holding onto it closer too. Both of them are pretty special to me though! I still remember getting the cartridge sent in the mail as a surprise from my parents one morning and being amazed by the yellow colour… ^_^ it really was easy to impress me as a little kid, huh…
So what about you? What is it about DK64 that just stuck?
