Banjo-Kazooie is a game I've played for years, and will continue to play until my 64 breaks down.
Banjo-Kazooie was the prime of its time, and still offers more fun than some newer games coming out now. So, let's get started.
Graphics: 94/100
The graphics were great for the 64, but some of them were a bit less smooth than desired, and some of the textures didn't have enough work put into them. If you're a big critic of that, the X-Box 360 version may be for you. Other than that though, in this game you'll find many smooth animations, glittery effects, and over-all awesome eye-candy.
Audio: 100/100
The sound effects is what we'll start with. They were incredible! I loved how every voice effect and talking sound fit with the character it belonged to; But the music really takes the stage here. Themes like Treasure Trove cove and Click Clock woods will have you dancing while you're trying to play! And others, like Mad Monster mansion, will send chills up your spine.
Game Play/Controls: 100/100
As with all 64 games, the controls may take a little while to master, but you shouldn't have trouble for anymore than 5 minutes. They were laid out much better than DK64, to be sure! And the Game Play was superb. Nothing about the game was way too hard, but it wasn't a walk in the park either. Just right, the way I like it.
Story: 100/100
It's a classic story, that doesn't go too much in depth, but brings a more fairy-tail and light twist to the game, which makes it fun to play for all ages. There could have been more story scenes, but the talking between characters mostly covered that.
Overall: 98/100 (10/10.)
This game is a good pick for any age, and a great game to start playing at any time you feel like it. For its price, it's the best there is.
