While other companies roll out the savings to celebrate holidays and new game launches, Valve's themed its latest after the humblest and most unassuming of all roots: the potato. Then again, the simple confection's been instrumental in keeping humanity from dying of starvation over the years, so we think that might be worth a few slashed price tags. Gamers have quickly discovered, however, that this isn't merely some goofy Valve theme. Well, ok, it's still pretty silly, but apparently potatoes have infested each of the formerly spud-less games. Why? No idea, but there's already a wiki dedicated to it.
