The majority of of Valve president and co-founder Gabe Newell's keynote address yesterday at the Games for Change Festival was dedicated to his perception of games as educational tools. And that was fitting for the event, which is dedicated primarily to the educational and socially beneficial elements of gaming, and fitting for Valve Software, a company known most recently for releasing a game steeped in science.

Newell explained: "The interesting thing about Portal 2 is it doesn't sort of fit the traditional simplistic model of what a game is. It's not a collection of weapons. It's not a collection of monsters. It's really about science. It's about spatial reasoning, it's about learning physics, it's about problem solving. And often, during the course of the game, you're going to be solving problems with somebody else. The social model inside of it is collaborative and not competitive."

After rolling a short clip of the game for audience members, Newell went on to profess, "There seems to be this distinction between games that are educational, and games that are going to be commercially successful. I'm not really sure I buy into that." Citing sales of Portal 2 as proof, Newell pointed out that Valve has seen "$165 million dollars in gross revenue" from the game since April 18. "We can do this. We can make educational, commercially successful games, which are gonna help us both on the game side and on the educational side." He reaffirmed this to me in an interview after the speech, saying, "I just don't believe in this distinction between games and educational games. A lot of times [the label] 'educational games' is a way of being an excuse for bad game design or poor production values."
