Ah, how I wish I was game dev instead of working mostly on Java backends for large financial institutions (and actually spending most of the time in meetings).
I am pretty interested in the modding Minecraft with Scratch part. I have found some abandoned projects. Can you point me to what you have used that worked for you?
Happy it worked for your girl and little scared she started at 5. I have two boys, one is 7 and the other is 4. The younger one is inseparable from the older so I wonder how it is going to be different for him.
I have been thinking about who gets to actually program. For now I am happy that mixed routine where we regularly switch works for him (he seems to be happy and engaged) and so I think I will continue this way for some time before I experiment with it.
I see that the best results we got were when he actually himself figured some stuff and made it by himself. His first machine -- ugly chest to destroy unnecessary items with a noisy clock that runs constantly whether there are items or not -- is still occupying middle of main room of our hobbit hole but I don't think I will touch it, because he was so happy when he got it to work.
