I go by the handle BlueAppaloosa, and I teach at the college level. I teach Game Design and Game Programming courses at a community college, and Programming for Non-Programmers at a big university. Games (probably obviously) figure in to all of my classes. We mostly make games, but also sometimes play them for analysis in the Game Design class.
I have been playing games on and off since I was a kid. I started making games around five or six years ago, and still do when I have the time. I've been studying games and learning for almost as long, thanks to my mentor being interested in the topic. I'm always interested in the ways people are using games to teach, both in and outside the classroom.
