I found another blog post discussing video game canon. Here. I found it interesting, as does the author that real time strategy is not included in the games. Among computer gamers real time strategy is a very popular genre with such titles as warcraft, starcraft, and age of empires. It is also a very distinct genre but the canonizer classifies warcraft as rpg because it is set in a fantasy world and tells a story. But the game play is definitely real time strategy and i think it is important to not ignore this distinction.
