Definitely a game worth keeping your old Nintendo 64 for. Great adventure game!
I was too absorbed in this amazing world Rare created. The worlds were colourful and so imaginative. The characters were interesting, and unique. The game had some very funny comments, particularly from Grunty, which seem to make the game suitable for all audiences not just kids. It was just the right amount of difficulty, of course the puzzles were not as hard as Zelda: Ocarina of Time but there were still some frustrating moments.
It's great how Banjo and Kazooie work together. I love their attacks and their friendship makes me smile :)
So, this game is very similar to Super Mario and uses the same forumla, but this game completely shines on it's own and is definitely worth playing if you own a Nintendo 64.
