Ah yes. I wrote a game (text-based "sports" sim) in Python and wxPython roughly eight years ago that still has a small, but hardcore community of players. I started on a "version 2" of the game about six years ago. Anytime I want to learn a new language I try and implement "version 2" using the new language. As a result I've learned Ruby, JavaScipt, ActionScript, Scala, Clojure, Lua, Haxe, and a ton of frameworks/libraries associated with the previous languages. It's been an absolute blast, but I still haven't released "version 2" yet.
