From Brainy Gamer
"Could I have chosen a game to stand by itself, with no accompanying text assignment? Maybe. I thought about Bioshock. I thought about Planescape: Torment. In the end, I chose Portal because I thought it would make a good start. A good first impression. A lead-off hitter, if you will."
"Deploying a game for an entire cohort to play at the same time requires more problem-solving than you might expect. We ultimately decided that hardware, installation, and licensing issues were complex enough to dissuade us from teaching Portal in all sections of the course this year; so I and a group of eager colleagues will play the game in our sections to work out the kinks. I don't want our first college-wide experience with a game to be plagued with problems."
