Alright, time to put in my two cents on the whole Rare/DKC debacle.
Whether you agree with it or not, Rare DID bring back the franchise into the limelight. Nintendo wasn't doing much with him at the time, except the occasional spin-off game (like DK 94), and was mainly a bad guy Mario saw at the end of each level. Sure, everyone remembered Donkey Kong, the GAME, but not THE CHARACTER. Mario was the one remembered and celebrated.
Then came Donkey Kong Country and finally gave him the personality and presence he deserved. The game did wonders for his reputation. People who grew up with the original game suddenly remembered and liked this game, while those that played DKC suddenly appreciate the character and his own legacy.
The gameplay may not have been groundbreaking, but it worked. It was addictive, fun and easy to get into.
The sequels (minus 64) polished the game even further and now we had a great franchise to remember.
If it wasn't for Rare developing Donkey Kong Country, we wouldn't have DK as a playable character in all the spin-off games (Yes, I know we had DK Jr. on Super Mario Kart, but that was the Jr. version) and we wouldn't have gotten Jungle Blast and DKC Returns, the games EVERYONE loves to death.
Like it or not, Rare set the stepping stones for the character to follow, and what we got was something truly great in the end.
I won't argue that not everyone liked the games, just saying that credit should be given here.
