Recettear is a game about an item store, the girl who lives in it, and the fairy whose job it is to make sure that the girl doesn't burn down the item store by accident.Official site.
So I found out about this game after reading this article about the demo at HG101 and I've been pretty interested in it, and the company doing the (really good) localization, since.
Got around to downloading the demo after hearing that it had been picked up for distribution on Steam, and it's actually really quite fun and entertaining. I recommend you at least try it (the demo takes a couple hours to finish and shows you the first week of gameplay.)
Capitalism, ho!
