The Library is the Snow mission is what holds this one back for me. But this has the best music in the series.

Halo 2
Halo 3: Prologue
2
Halo 3
Ending of this game alone gives it a 10.
3
Halo: Reach
Not a fan of the power ups but the story is cool.
4
Halo 3: ODST
Neat single player side-story. Way more difficult though, and started a weird trend of running in Halo that I don't like.
5
Halo 2: Anniversary
Prefer this to Halo CE Anniversery due to the more faithful artsyle but still has a few things that bug me about it.
6
Halo: Combat Evolved Anniversary
'New' graphics are gross.
7
Halo 4
Gameplay tries to emulate ODST and Reach when it should have just focused on being a good Fallow up to the original trilogy, in that case it's nothing special.
