I believe it may have been the most fun game I have EVER played. No joke. It's not racing game, it has maybe 5 races in the whole game and playing through it is so unique.
The graphics really are some of the best graphics around but because of the coloured, cartoonish nature of them they'll never really be appreciated. Every single object has such an amazing level of detail to them and they're all done in such a cool fashion. Like, hills are stitched together and trees have bits of tape holding them together.
The humour is still present, although, it's a bit more mature than before. Playing through the first B&K you'll notice it's all very childish. "Grunty brushes her teeth with fishy toothpaste!". While N&B parodies itself, the story, previous games and even other games. It has some actual laugh out loud moments.
The gameplay is the best part about it. Every challenge can be tackled in your own style and it leads to very creative thinking without ever being too complex. There's a couple annoying ones but overall the challenges are thought out very well. Nothing's more fun than flying around and shooting giant, inflatable dinosaurs.
So in short, the game fucking rocks. It's humorous, has amazing graphics and is insanely fun to play.
