For the Nintendo '64 gaming system, the two pre-eminent adventure games were Mario and Zelda. Those games enthralled players with their tight gameplay and interesting stories. Unfortunately, DK '64 doesn't have that same tight gameplay, and the story was never the strong suit of the series.
The problem with this game is obvious after about 30 minutes: It's all about collecting items, and very little else. Whether it is coins, tokens, or bananas, this game quickly devolves into little more than a scavenger hunt for miscellaneous items. Making matters worse is the fact that EACH CHARACTER needs to collect each item to unlock certain features. The game is tedious enough playing just as a single character, but add in the four others and it becomes ridiculous.
The music in this game is engaging (the DK Rap might just be the highlight of the whole experience!), but other than that nothing really stands out. If you don't mind collecting item after item, you'll like this game more than I. If you prefer a developed plot, however, than stay away at all costs
