Your money is precious, like a precious, precious flower, made out of a precious crystal of some sort. We understand your hesitance to drop a wad of cash -- or in this case, a lone $20 bill -- on unfamiliar IP. Fortunately, so does Runic Games, developer of the recently released top-down RPG Torchlight.
