The problem with this, like every other Halo game after Halo 1, was that they focused too much on multiplayer; and spewed a short and unsatisfying campaign to go along with their main focus.
Sure the cutscenes had great graphics but they barely made sense. Why did the Covenant go to Arcadia? What was the point of throwing the flood in there? Why are the Spartans viewed as immortals?
The canonical errors are atrocious, even with a Bungie consult. And this crap about the Halo Wars team playing through all the Halos and reading the novels is total BS. If it were true this game would have been much better.
I have fun in multiplayer, but I find myself struggling to accept the campaign for what it is, it seems all they did was throw it together just to give the leaders a story, and even at that where's the f'ing Chieftain???
"Die?"Kurt laughed."Didn't you know?"he told the Elite. "...Spartans never die."
