It looks like Java and Python are the main options, both applied to game programming. There are also classes using the Lego Mindstorm scripting language, and Scratch. Slashdotters, I assume you've run into this question before, and I could use the help. Programming tools have changed a lot since I was learning SmartBASIC on a Coleco Adam as a kid. I want to recommend something that will be powerful enough to show him the unlimited possibilities in programming, but easy enough to maintain his interest and not discourage him. What do you teach your kids? What has been effective?"
