Aw man, one is unable to vote for more than one game!
Although that is probably to prevent people from just selecting all the Rareware-made games at once.
Ah well, I decided to pick
Because I just happen to have the fondest memories of that one.
I probably also played DKC3 the most out of all the DK games, now that I think about it.
Especially the snow levels. In fact, whenever it's snowing outside, the very first tune that comes to mind is Frosty Frolics.
Although really, all the Rareware games were really close, it was hard for me to choose a favourite (others would be DK64, DKC, DKL, DKC2, DKLIII, & DKL2, probably in that order too!)
additionally, I don't much care for DKCR and DKC:TF, and I never played DKJB
