I spent a lot of time this past weekend watching people (boys) play Call of Duty. A lot of time. Like, an inordinate number of hours. At this point, I know which level is the most fun to play with friends (Shipment), which weapon is the most effective from a distance (grenade launcher), which method of killing is most satisfying (a run-by knifing), and which XBox Live player has the best name (Brodie1Kanobe FTW).
At this point, I can only make one conclusion, and this conclusion is that Call of Duty alone should decide the outcome of all future wars.
