Now, decades later I’m finally pursuing that little dude’s dream, although games also lost their luster for me on the intervening years...
Yeah. I still like writing small games from time to time, mainly just to serve as programming exercises or for fun if I'm bored. I had to accept at some point that I don't have the wide variety of skills needed to make my any of my dream games on my own (and also the time commitment to make a whole game by yourself can be insane). If I were to make a serious effort to do so, I'm pretty sure I would just be disappointed and feel as though I'd wasted my time because the final product wouldn't live up to my fantasy. To realistically do it, I'd need to either sacrifice a lot of creative control by collaborating with people, or wait until I've eventually acquired enough skill in the areas of art and music et cetera to pull it off by myself.
Now that I've grown up, my primary interests lie in virtually all aspects of computer science, and I no longer consider making games to be much more than a hobby and passion project to spend my free time on. I only wish I'd have had a mentor of some kind in the world of CS, so that I could have gotten into it earlier in my childhood. Major props to you for being an awesome uncle :)
