Halo 3 
Story
The story of this game was excellently well-written and well put together. It really brought the game full circle, but I do believe that there could have been more added, to help smooth it out. Overall I thought it was short, but good. 8.5/10
Design
Each part of the campaign flowed well into the next part, although I didn't like the transition between the end of The Covenant and the beginning of Cortana. The game was designed well, and had cutscenes every time there may have been a flow problem. 9.5/10
Gameplay
Halo 3 certainly has the best gameplay. The controls are easy to get used to, and fit well with the controller. This game is fun on both the Single and Multiplayer level, with something different that can happen every time. The multiplayer of Halo 3 is the best out of any game. The people over at Bungie are the masters of multiplayer gameplay. 10/10
Graphics & Sound
Amazing. That is all I can say. The graphics are beautiful, while the music is totally epic. All of the gun sounds are very realistic, and work well in tandem with the vibration controls so you can really feel how much of an impact this gun can make. SMG the most of all. All of the marine voice overs were excellent, funny when they could be, and serious when they had to. The only thing that brings score down here is Miranda Keyes' voice. I think that it was not well done, and although it worked, it could have been much better. The chief also had a bad moment, when he said "The rings will kill us all". Totally forced, it should have been redone. 9.25/10
Overall
Overall, this game was absolutely amazing. Although it disappointed many, It made me fall in love with Halo all over again. Kudos to you, Bungie, for being totally awesome like that.
