It's one of those games that you read all about before it comes out. You preorder it and simply hope that it doesn't disappoint. I've finished Act 4 on the single player and spent a great amount of time online. It's fantastic! Even though this game is immensly different than Halo 2, the first thing most people asked me is how does it compare to Halo. The primary reason is because Halo  has great replay value. Online is where it's at; at least for me.

I've been able to play for a few hours straight and not get bored. Whether this game can stand the test of time like Halo has is yet to be deteremined, but one thing is for certain, it's a ton of fun now. I can see myself playing it for months to come.
