In my opinion you shouldn't publish every game you ever made but the ones you think are worthwhile playing. If you publish a game you need to go the extra mile with a help function and a credits page, maybe even localization (which in my opinion has the extra benefit all your texts are in one place and easy to find should you - and it is going to happen - discover a typo during game play). I myself have started about 30 games over the years, most of them playable, but I published only 6. The last game I didn't publish felt more like work than like fun and I had to admit to myself the idea wasn't as brilliant as I thought.
