Hmm...........no, they're definitely not redundant, but to begin with, they had a pretty low economic value. Or more like, the western release gets a pretty horrible deal when compared to the original DMM version; they pretty much fill their tubs with free gems, while we're post apocalyptic and scrounging for everything we can get.

Despite that, it's pretty much one of the main motivators to keep us free/cheap to plays in this game. That alone gives it some value.
