What's your opinion on each Halo game?

[Barozi]

Halo CE - Great campaign; addictive offline multiplayer - 9.8
Halo 2 - "only" good campaign (still great in co-op); better multiplayer due to Xbox Live - 9.2
Halo 3 - better campaign than the 2nd game, but not as good as the 1st; awesome multiplayer - 9.6
