What was your first project?
Mine was this Tetris game I made in the Warcraft 3 level editor in 2003 when I was 14. It wasn't the first map I made in Warcraft, but it was my first time using the scripting language (JASS) instead of the GUI. Level editing in WC3 was what initially taught me about things like variables and loops, before I ever got to a real language like Java.
