You say you got everything you wanted that would help you, maybe that's one of the reasons. Scarcity forces creativity, there's some challenge too.

Also things have developed to be kind of complicated compared to the good old days when commercial games were made by some dude just like you in his moms basement, maybe from zero to completion.

Most things have been done already and done well by either very talented inviduals or companies with lots of people. It's not fun to reinvent a wheel, especially if you're doubtful that it would be any better than what's already out there.

Getting older also gives you self confidence and/or lowers your need for validation from others. Impressing a tiny fraction of anonymous people on the internet doesn't change how you feel.

If you got good at what you're doing, then you know that you could accomplish what you want and how to go about doing it if you just decided to do it, that's mostly not motivating or challenging, more like a chore.

I'd suggest starting a project with some kind of measurable outcome, such as trying to get your stack overflow score up, making some kind of utility that's faster than the existing ones (a faster grep, an xml parser, ..) or something like that.
