PAX is this weekend and all this week Xbox LIVE Gold Members can save 33% on Penny Arcade Episode 2.  Normally 1200, Penny Arcade Episode 2 is the latest Deal of the Week at 800.
Hothead is awesome. They're really, really awesome. The problem is... well... they're no Telltale. Their games are wonderful, but they take for-ev-er to release, whereas Telltale does them basically weekly. On the other hand, it has been a while since Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness - Episode 2 came out. With the Penny-Arcade Expo right around the corner, I'd expect to hear more out of the duo's adventure, and there's no better way to prepare than to play the latest episode.
