I can't go anywhere without seeing an ad for Halo 3. Gamespot is so far up Master Chief's... gun that they can't see Halo 3 for what it truly is. The third installment is way to over rated. The original was such a great breakthrough in the gaming world, but hasn't blown gamers away like Bioshock, Heavenly Sword, Gears of war, and the wii system. These are the games that deserve the true glory because it's taking what we have all already played and going far and beyond what we expect. 
So what did I expect from Halo 3? Simple. Better graphics, better story, more weapons, and improved multi player. And guess what, that's EXACTLY what I got. Now, nothing is wrong with this, it's just that Bungie didn't go beyond what I expected and thus not stacking up to what other next-gen games are doing. The attention it's getting is like this game is going to change my life forever. Not even close.
Let me use a good example of this. The first time I played God of War, I was blown away. I then played the sequel and was completely disappointed because it was the same thing. I oddly felt this way with Halo 2. Maybe it's just the first person shooter becoming the same crap over and over. 

I give Bioshock the gold in the FPS this last year. At least those guys are able to push the FPS instead of making an armor suit that I almost never see look more detailed.
