That was a good game. Very good. Actual emotional attachment to a character. I like when games do that and prove that they can tell just as good a story as movies or books. Then again, kicking ass with the SAW and Incinerator Cannon is just as fun.
People always say shooters have bad campaigns. Well, Halo actually does campaigns very well. I'm sure we all remember 343 Guilty Spark. It sent chills down the spine! And seeing how John and Cortana interact in Halo 4...I loved it.
