According to the ESRB, this game contains: Animated Violence, Comic Mischief
Parents have nothing to worry about here. While Rare may be testing more risque water in the future, Banjo-Tooie remains completely kid-safe and in-line with the wholesome quality parents tend to expect from the big N. The game is bright and colorful, with no violence except for monsters that disappear in a puff of smoke when pecked by Kazooie and other similarly harmless stuff. Younger children will have trouble with the game's difficulty, but older kids shouldn't have too much trouble. No sexual content whatsoever, and though the writing might be a bit on the smart-alecky side at times, it's harmlessly vanilla compared to what you see on the average cartoon or sitcom.
Gamers in general cannot go wrong with Banjo-Tooie. It's an extremely polished title with an insane amount of technique and depth. The variety in the gameplay will keep you glued level after level, and with the amount of extras like the minigames and four-player support—even FPS deathmatch—this is as close as a game ever comes to being a guaranteed hit. Combine that with more than 30 hours of gameplay, and you've got a game that will make anybody happy.
Nintendo fans are required by law to go out and get this game if they haven't already. Releases are pretty sparse for the Nintendo 64 to begin with, and Banjo-Tooie is a five-star affair. It's a must-have for any Nintendo library, and there is no reason on earth not to own this title if you're even the most casual Nintendo follower.
Banjo-Kazooie fans will be lifted to a higher plane of gaming existence with a title that indeed surpasses the original's accomplishments. It has everything you liked about Banjo-Kazooie, and adds an unbelievable amount more without changing the charm and appeal that made the game so great in the first place. An almost perfect sequel.
Platformer fans will not find a better 3D game on any system, anywhere. If you like platform action and adventure this game is the pinnacle, the summit. Both your thinking and jumping skills will be put to the test, and you'll love every minute of it.
Technophiles will be pleased to learn that Banjo-Tooie supports Dolby Surround Sound as well as a 16:9 wide-screen display (for gamers with a wide-screen television).
