Donkey Kong 64 was one way to ruin Donkey Kong Country. The other was to use it as the basis for a browser-based online game where monkeys with yellow exclamation marks over their heads hand out quests to bored children. Monkey Quest was Nickelodeon's attempt to get some of that sweet Club Penguin cash after people realized tedious MMOs layered with psychological trickery could manipulate kids as easily as adults.
