DK64 is the greatest game ever, well one of them.
I love it, I think you'd like it.
By the way, Kirby's Return to Dream Land is a Wii game, not a VC game, just on the eShop.
Definitely get DK 64 and Kirby's Return to Dreamland (If you can't find it in the stores) or Kirby 64 if you can't get the Dream Collection with 6 Kirby games.
