>Favorite Game
Each game does their own thing well or has aspects about it that I like. Purely as a game, I'd say I like DKC2 the best. Aesthetically, I like parts of DKC3, I adore Northern scenery and culture. With Water World being one of my favorite tracks from the series. It encapsulates a "drowning" or unsettling murky waters tone perfectly. I also don't mind the gimmicks and like the level variety in DKC3, it's not DKC2, but it's good at what it set out to accomplish and stands out nicely on it's own.
DKC2 while darker, has a lot of good scenery too, only that some of the levels tend to feel "samey" or can be annoying to play at times particularly in the first 2 worlds. Krazy Kremland is possibly one of the best areas in a video game in general.
>Favorite Kong
Probably Chunky, although I don't care for DK64. I like his design and something about him looking big, buff, and cool, but being nervous, cowardly, and childlike is sort of comedic and appealing. And Dixie's pretty cute.
>Favorite Soundtrack
DKC2 has a good amount of quality tracks overall, but I really appreciate some of the songs in DK64 and DKC3. As I said previously, Water World is one of my favorites.
>Miyamoto Design or Rare Design
Rare design all the way. Although the Miyamoto design has it's own charm and I wouldn't mind seeing it used again in some way.
