Whether real or not, it does raise a question I've been wondering about for a while now - what about a f2p game that did state upfront that while playing, you are mining; so the more you play, the more it costs you. No IAP, no upfront costs, etc.

Obviously it would not be suitable for some game types (anything 3d heavy, basically), and has obvious battery/temperature implications on mobile, but it does seem to provide a plausible additional option for monetization.
