As promised in my Halo 1 review, I differ from many reviews. I've played all 3 in order in coop.

There are a ton of reviews, and it's easy to grab one and get the general gist - better graphics, new environments, weapons rebalance, fighting on Earth, playing a good part of the game as the Arbiter, etc.
I totally agree with all of that - many of the most memorable parts of the trilogy happen in Halo 2.
Where I differ is that I felt that the story, taken in context of experiencing all three was perfect - not too short, very dynamic and the "cliffhanger' ending was perfect for Halo Canon and totally sets up Halo 3.
What can I say - It's an experience that I would be happy to repeat - taken as a series, the set is probably the most enjoyable coop experience I have ever had.
