Ultima and Tabula Rasa creator Richard Garriott shared an interview with Gamasutra and talked about games as an art medium, calling them a 'pulp fiction', amongst many other subjects:

"Are games art? They can, and I think, should be. How much "art" there is in a game is up to the developer.

There's a lot of games which I'll describe as just pulp [as in the magazine genre], but absolutely: I think there's lots of great art in games. A lot of my favorite games, actually, are the ones we think of as the most artistic. Games like Myst, or American McGee's Alice, Abe's Oddysee."
