I've been jumping around a few PC games thanks to my new beefed-up desktop, but the main game on my mind at the moment would have to be
World End Economica Episode 1, a visual novel penned by Isuna Hasekura (Spice & Wolf),
with the English translation being released not too long ago (I just so happened to buy the Japanese version of Episode 2, hopefully a translation won't be too far behind).
Definitely going to have to find time to finish it. The first 10 minutes probably taught me more about economics than a high school commerce class could.
