I always prefered Yoshis Island. I has both games when they were released.
DKC was very popular, I remember when early screen shots of the game were released in magazines people were frothing at the mouth thinking it was a next generation game for N64 but when people realised it was for SNES it blew peoples minds. A really good game to boot but a simple Mario clone.
Yoshis Island had some extra gameplay elements with eggs and the jumpe the visual style was also a treat. Please release it on the VC soon!!
