The Pink Godzilla guys have created a trading card game where the goal is to develop video games. In case you don't live in Seattle, Pink Godzilla is an import and retro store (You might have seen them in Tycho's posts at Penny Arcade) that carries a ton of classic games in japanese titles.
Anyways they've made a trading card game that is debuting today at PAX. If you want to check it out, go to www.pinkgodzilladevkit.com , it's looking pretty good if I say so myself.
(Disclaimer: I work for pink godzilla, so this is kind of a shameless plug, but still worth mentioning I think :)
