Well, the author of the original series also wrote World End Economica, which is basically the same thing... just without any actual wolves.
Steam store page blurb:
From the author of Spice and Wolf, Isuna Hasekura, comes WORLD END ECONOMiCA. This is the first episode out of three part sci-fi/economic thriller visual novel set on the moon.
I just love the fact that "economic thriller" is actually treated as a genre with this guy.
