The making games part, absolutely. I have probably over 20 games that nobody plays. I have updated games at the request of the only person who plays it. I once made a game that I thought that no-one at all played but then got feedback from someone to say that their entire office was addicted to it. Last week I got an email asking for the solution to one of the last levels of a game I made around 2000-2001 (which I really should reply to :-/ ).

There was another thread yesterday about coding for the joy of it, I entirely support that too. I have written a few Dweets in my time, but the author of Littlejs is one of the masters of the form https://beta.dwitter.net/u/KilledByAPixel/top
