This has the potential to go horribly wrong... Judging something by its artistic merits is a lot different than choosing your favorite title, best selling title, and popular title. The day we see COD representing video games as art is a dark day indeed. Why it's there I don't have a single clue... Someone didn't do their research at the Smithsonian..... There is good art...and then there is bad art.
Either we validate the medium as an art with well thought out choices, or we damn it by showing the world "this is what gamers consider art" A.K.A COD, Halo, and a number of other titles that really have no business being on that list.
I don't mean to sound elitist...but this is big. Do we really want to be known as a medium that gives artistic merits to mediocrity?
