I've finished one "native" game in C++ and SDL a few years ago (Space Invaders clone.) I've started countless games over the years. None of them are worth giving details on, though.

Ages ago I made a couple of browser games in javascript, that was my first "real" attempt at programming. I made a randomized Trumps game and one where you had to fight a dragon in a maze but you could only hit it from one side. Someone actually copied it, I was thrilled.
