I love Super Mario 64.  Its a great addition to the Mario series.  Without this game, I wouldn't have started to like Mario.  So, here is my review of the game.  

Graphics: 7
Compared to other N64 games, the game's graphics are pretty much the same.  And there's just a bit of the graphics that bothers me.  Maybe its just me though.

Sound: 9 The game's music is awesome.  Bob-omb Battlefield tune is famous to many gamers.  And the final boss theme, is just magnificent.

Addictiveness: 10 I love finding all the secrets and glitches in this game, and love playing this game over and over again.  It's a classic almost everybody loves.

Story: 6 The game dosen't really have much of a story to it, but it has a bit.  Peach baked a cake for Mario, so Mario goes to the castle and  sees that Bowser took the Power Stars, so he goes to get them and save Peach.  The story is only slightly bad.

Depth: 9 Once you beat the game, if you have less than 120 Power Stars, than there are still more to go.  It takes a while to get all of them.

Difficulty: 9 This game can be very hard a lot of times.  But other times, it can be a breeze.  The controls sometimes annoy me though.

Overall Rating: 9.5  Thus ending my review.  (This is my first review on a game btw.)

This is a very good first review! I really enjoyed playing this game too. The only thing I would suggest when writing a review, is that you should expand on your ideas a little more. In other words, add a little more detail. Other than that, it is pretty good! I can't wait for your next review! Keep up the good work dude!
