Banjo - kazooie is on of the most fun games on the N64, the levels are great, not very original but they are all fun and well thought with lot's of thing to do in them.
The gameplay in this game just feels so nice it's one of the best things about it.
The story, considering it's a kid game, it's just right, it's the tipical tale of the witch and the good guy (I don't know what I mean) but it's nice.
Banjo and Kazzooi together have a great amount of moves they perform and are very usefull thruout the game. And anothr good point that makes this title good for almost anyone, it's easy enogh for kids, but it's a long game, so even though i's very easy, it will entertain an adult for a reasonable time.
