This is of course true too. People don't think video game composers deserve to have articles; so they argue for non-notability.
Whether this should be the case is another story. I consider this to be an abuse of the rules.
---- That's an example of a fairly common human prejudice against new creative genres. Novels were held in light esteem while Henry Fielding and Jane Austen were writing them--light entertainment for adolescent girls. It wasn't really until Thackeray that the genre became respectable reading for serious adults. When motion pictures were new they were mostly regarded as light entertainment for working class audiences. Partly as a result, nearly 90% of the films from the silent era weren't curated and have been lost forever. Of course 90% of every genre is crap and the Pac-Man theme will probably torment me for the next three hours. But Austen was nearly forgotten for fifty years after her death--I wonder what critics of the next generation will say about the theme music from Morrowind. -Durova
