I bought it day one and was so hyped for it, it was kinda ridiculous actually. I loved DKC and especially DKC2, and Rare was on a roll on the N64 with BK, Goldeneye, etc so I thought it couldn't possible go wrong.
But it did.
The start of the game is fine. In fact, the first level (actually, make that the first two levels) are good fun, have great music and at this stage you're thinking that it can only get better. Except it only gets worse. You see, you get more characters. And when you get more characters, you get more bananas to collect. And more coins. And more golden bananas. And more fairies. And more and more and more.
By level 3 or 4 the game becomes way too convoluted. It goes from being a fun 3D platformer to a total collectathon, and it's totally overwhelming. You basically have to complete each world FIVE TIMES. And these are freakin' huge worlds too, filled with all sorts of challeneges, which are by the way totally hit and miss. The barrell ones are fun. The rings too. But please don't give me crap like the beaver round-up game. Holy shit that was bad.
Some would have gotten a kick out of it, for sure. It's a massive game and those who collected everything may have found it pretty rewarding. But for me, it's just dull. Too much collecting and not enough fun.
