I love this game, it is so much better than it's predecessor. The campaign was great, the touchups they did with forge makes it so much easier to use, the ranking system actually does something now which is cool, matchmaking seems to move a little better and they don't have the ridiculously overpowered weapons as in Halo 3. So far, I'm glad I bought it. I only have two more achievements to unlock and I'll have 1,000 gamerscore and I have 4 out of 5 rewards ( I don't see a killtacular anytime soon in the future for me lol). It's an overall great game, I love how they did it.
