What's great about game tutorials (imho) is that they are really motivating for young people to follow when they learn to program. You get some very interactive and sensory feedback, get to have fun with something you made and learn a ton in the process.
I agree. Anything that gets people interested in programming is good for the industry. Typically I try to steer people who are interested in trying out programming to scripting languages first. The benefit here is the learners get an expedient path to gratification. It's important that people experience the gratification that comes from building something before the ugly truth about how horribly complex these systems are sets in.
We can never have enough of those.
