I feel you. My son is still younger, but I have similar fears.

As any good husband would, I bought my wife an old SNES for Christmas a few years ago. And my son loves playing Super Mario World on it.

So I thought some time back, that it could be a great father-son bonding experience if he and I were to code up a simple pixel-style 2D jump'n'run together that he designs and I program.

Except that he's been taking way too great a liking in it. He's kinda obsessed with the development of that game already, and now I'm worried that I turned him onto something that I pray to God will never become his career...
