I've been programming in one language or other, since the 1970s. I'm still in the "let's make stuff" stage. That includes making the tools to do whatever that "stuff" is - image editor, animation editor, etc. I've "finished" just a dozen games and simulations over the years. For me personally, it's all about learning and, because I switch APIs every few years, there's no end to the opportunities to find out "How can I do that in [fill in your API]?"
This pretty much covers me as well. Including the 1970s ;-)
