There are two problems: (1) hardly any History of Art and Architecture people play competitive multiplayer games, which are far and away the gaming zeitgeist, (2) you can't be taken seriously in a History of Art and Architecture program taking a positivist or normatively-positive approach to video games.

There are a million interesting things you can say about architecture in video games! There are more people that can close their eyes and visualize the exact locations of the plants in Counter-Strike's Office map than there are people who can visualize any other building anywhere in the history of the world, other than their own homes. And it would be really interesting to just talk about the design of levels as spaces for killing in a fair way, as opposed to say, architecting a museum or a school.
