When I started with computers, I had to bust my ass to get any time with any machine at all and there was nobody around with information or guidance or knowledge.
The first thing I did wasn't play video games. I learned about BBSes. I learned telephony, phreaking, networking. I learned BBS software. I learned people. I built a BBS. I built a multi-node BBS. Then I moved on to writing engines for websites to do things I needed (like financial transactions, databases, etc).
I started with computers around the age of twelve and didn't really get into video games a bit until my twenties and a lot until my thirties.
Meanwhile, I have seen kids in the last fifteen years primarily use the computer for porn, video games, and social networking... and that's all they do. Not once do they give two shits worth of thought about how things work or why they work or to start taking things apart and looking under the hood. Kids are raised as consumers of content; not creators. In fact, they are punished for being creators. Inventors. Discoverers. Hackers.
Most of today's games don't have the same design. They're not really presenting you with intellectual puzzles for the most part, so much as advancing to the next level. You aren't having to figure out how not to be eaten by a grue, and even mazes are rare in today's games--things that require real use of thought or memory or other mental ability rather than just reaching for the next reward.
