Well, I've been learning and using http://www.libsdl.org/ a lot lately. It's pretty awesome. After I get the essentials down I'll implement http://box2d.org/. Other things that have interested me lately, http://en.wikipedia.org/wiki/Parkour & http://en.wikipedia.org/wiki/Free_running, http://en.wikipedia.org/wiki/Third_wave_ska#Third_wave_ska, http://en.wikipedia.org/wiki/Europa_Universalis_III and a mod I've been working on occasionally for NV ( http://www.newvegasnexus.com/downloads/file.php?id=39537 ). I try to keep myself occupied. Oh, and I have a physical today so I'm interested in how much ball touching will occur.
What about you? What interests a Battling Creature.
