I'd just like to add my admiration to the glowing memories of Banjo-Kazooie. The tightly designed levels were great in that there was always so much to do & not far from a collectible, enemy, or challenge. Special mention must go to the wonderfully designed Click Clock Wood, and the consistently excellent and memorable soundtrack.
It's a shame that they were never able to fully implement Stop N Swop, one of the great mysteries of the N64 generation. Wozza and Ice Mario were persistent in their search for the truth and uncovered so many additional unused features and ideas (Bottles Revenge anyone?) that they even added to the legacy of the series.
Grunty's Revenge was a good effort at bringing the Banjo gameplay to the GameBoy Advance. Banjo-Tooie was probably too large, which detracted from the ideas it had and some of the clever integration between levels. Oh, and the walking innuendo that was Jolly Roger and his whole level! Rare's sense of humour at it's finest!
How it'd be great to see another proper Banjo platformer. Rare's priorities don't seem to be on that type of game at the moment, but I suppose you never know what the future holds!
