Best damn thing i've played!
Best game i have played all year, there is so so much that Bungie out into this game that there is no limit to the replay of this game. This to me is one of the greatest if not the greatest games of all time.
+Best video game story line ever, i could see this being a bed time story in the future.
+Audio is top notch, it sends chills down my back every time i hear music from the game. it also really puts you into the story.
+Graphics make me scream "holy crap!" and i don't even have an HDTV!
+multiplayer is the best around most fun and frustrating thing ever! and i love it!
+Bungie did and amazing job at integrating Bungie.net and Halo 3 into one. Now you can track your ingame states,screen shots and movies all from Bungie.net with extreme ease.
+Saved films is like a dream come true, i love it!
+Forge is awesome! Not only can you mess with the map and create some of the craziest and funnest things ever! but you can play games while you edit on the fly.
+I LOVE the fact that when you earn achievements and ranks in the game you don't just get GP or ranks, but you also get actual ingame stuff! (armor permutations)
+Online co-op is great and the meta game adds to the crazy amount of replay that this game already has.
-multiplayer can be the most annoying thing ever with lag< you shot him then he will turn around and kill you when you know that headshot should of got him...
?Halo 4 maybe?
