If you’ve been to PAX, you know that just about everybody hands out promotional swag. Most of it is pretty, but t-shirts, buttons, and temporary tattoos don’t really have much to do with the games they advertise. Nicholas Trahan, on the other hand, is a bit more thoughtful. He was handing out multicolored pens for Liight, a color mixing game from Studio Walljump. It also turns out that he’s a handy source of insight about the game’s inner workings, the art of feedback in game difficulty, and the secret origins of Studio Walljump.

The Penny Arcade Expo is right around the corner, and if history is any guide that means it’s time for this site to start giving shout outs to the PAX 10. So for the next week, your regular posting schedule will be filled with some of the most innovative gaming of 2008 and 2009. We present to you the PAX 10.
