I think the "competition" is much harder nowadays. When you have all the AAA games available, it's not that exciting to just get something moving on the screen.
Maybe something physical would be interesting? Like programming a led-strip (nowadays you have these where you can individually address the lights), robotic arm or something like that.
If kids are into certain games, maybe there's some opportunities to explore on the modding side. Like for the Euro Truck simulator you can bring your own graphics for the trucks. No idea how complicated it is to package those, but it would probably teach a ton of things.
