What's your favorite halo game?

Pleas tell in the comments why.
I would like halo 4 as the best because it has Spartan ops and master chief, but I hate prometheans and Spartan 4s. Otherwise, reach is mah fave.

Halo Reach by far.
I think this is supposed to be in the Poll Discussions forums too bro XD

A lot of people liked Reach, I started with it, so Reach…

Halo Reach !!! For ever !!!
