Halo is known for its wacky science fiction stories. Its about slipspace ruptures, mysterious ringworlds, intergalactic zombies, exploring strange structures, guerilla warfare, ect.
Reach was about a few soldiers walking across a farm, walking across another farm (at night this time - crazy plot twist!), driving through a canyon, blowing up an enemy ship, saving a bunch of meaningless civilians, flying though a destroyed city, playing firefight underground, then playing firefight in front of the Pillar of Autumn. Oh and the whole game you're just flipping magical switches that are supposed to save the war.
The story was just so safe. It was bland. Gross. Nothing happened.
fuck.
