my opinion is simple, i have 2 kids 1 at 8 and other at 5
both of them don't play to video game during the week and not a lots during week end, ( like 1 or 2 houre max a week end ) and this is becose i don't want, i prefere kids outside playing with other than glued to a videogame or a computer.
sure it will be a good thing for him if you buy it a programming tool s like DBP and other program like 3d modeler. but in a way, kids as to incrase some social skill and to have a good health, they need to miove a lots and play sport or something like that.
learning programming is not hard and i m sure your kids will learn it fast, maybe some math theori will bug him a bit.
but when i had is age, i was a pro gaming and to push my ambition for the game, becose i didnt have a computer, i created some RPG like dongon & Dragon to play with my friend, that give me some logic skill on how to make basic game theoris and calcul.
but if your kid are not 5h on the computer every day after school and during week end on it too, its can be a good idea, but if you think the kids will lost himself into that like you say with is sketch, i don t thing is a good idea, he as to explore more reallity before falling into no real thing
If Zeddex can, you can. If you have an idea, make it.
