Overall: 1
This is worst than Sonic 06. The game was made to try and undo the damage Sonic 06 did and well it made it much worst. This is the most lazy port of Sonic 1. Sega should be ashamed to publish this. Sonic 10th anniversary was celebrated by Sonic Adventure 2 a good game, so what happened here for the 15th. 

Graphics: 7
The game looks great, not as good as the Mega Drive one but still look good. The animations are pretty good as well. They really hit the nail on the head with this and kept the style of game play. But that is it, the only thing that makes this games worth playing. So stay with the other ports.

Sound: 2
The music is terrible and will hurt your ears. The music you know and love, have been butchered and hurt a lot. I love Starlight Zones music, but when I herd it on the gba I was annoyed at how bad it sound. The music is bad as whole. After you here it, you will want to here the 16-bit any other port or remix of the levels music to make you feel better.

Addictiveness: 1
This game is not as addictive as the other ports, while the other ports you will want to play and play again, this one will make you not want to touch it again and put it a box to never be played again. At time you had no choice but now you would never play it.

Story: 1
The Story has not been touch at all, the story is that Robotnik as taken all of animals of South Island and its up to save all of the woodland creatures and make the world a happier place. The Chaos Emeralds only change the ending in this game and there is no super Sonic.

Depth 2
This would higher if was doing the original sonic 1. There nothing special l to keep you playing. There 2 versions of the game; Original mode and anniversary mode which only adds the spin dash which is pointless and I cant see why they cant add it to the original game. There a juke box which if have the gift of hearing you won't want.

Difficulty: 7
The is much harder than any other Sonic 1 port, why? The SLOWDOWN its everywhere and always gets bad when the you don't want it to be. Scarp Brain a level when there so much happening the game becomes so slow. If the slowdown was not that bad it would be playable.

Sonic on the gba is the worst Sonic game ever. With this being the only Sonic 1 on the go in 2006 is was good. Now there's a psp and a Nintendo ds port of Sonic 1 the gba port can be left in dust.
