I think it's fairly true to say, that in the early 90s only the geeky/tech smart kids had PC or were into PC games. In the early 90s there still weren't many PCs in schools, remember.
So the non-geeky kids stuck to their consoles, pretty much. As you know, the console experience is pretty much plug and play.
These days, every kid has a PC, laptop, tablet or all three. But there are still only so many geeky/tech smart kids using them properly and fixing them when they go wrong.
The rest want/need a console-like experience from their PC.
So I don't think that kids are getting lazier, I think simply that PCs are in the hands of everybody today, whereas in the 90s only a few tech smart kids would have really wanted one at home, compared to a PS1, XBox, GameCube or whatever.
