This is exactly my experience. It probably helped that I did just enough game design to be acutely aware of even less-obvious time sink mechanisms, but I don't think it was an essential feature of what changed. Even simple puzzle games and other things that aren't manipulative started to pale in the face of the realization that "hey, I could go fix a broken shelf or read a book or exercise and get a lasting benefit". It's not a sense of duty or anything else people would describe as "not being lazy", doing something fruitful just started feeling better. I still play games, and I'm happy with that, but the set of games has shrunk to things with ongoing interest and no grind, and the timing to stretches where I'm tired, stuck (e.g. at an airport), or playing with friends. I don't doubt that addictiveness is a real factor, but I think lots of horror stories about gaming and tech addiction grab the wrong end of the stick. I've seen a half dozen people take "young men now work fewer hours, and game for a similar number more hours" and say "obviously, games destroyed their will to work!" Meanwhile, half my friends have gamed heavily when they had crap jobs, short-term rented apartments, etc, and then stopped as soon as they got bored and found opportunities for lasting improvements. Games are a fantastic way to kill a lot of time comfortably, but that doesn't mean they override all our other impulses.
