As a complete aside to this thread, is book piracy in Russia as bad as these authors claim?
Open letter from a group of Russian-speaking LitRPG-authors
Sorry for a link to plebbit, but I have no idea where the original is, and I don't see a link within the thread. The funny (or perhaps not so funny?) element of the letter is that if you didn't know where to find pirated material in Russian before reading it, you sure as hell do now.
Not that LitRPG is anything much more than a subgenre of a subgenre, but these authors are some of the heavy hitters within what I'll characterize as the community. I think at least a couple of them are full time authors, so I'm not sure I believe the $700 monthly income claim, or at any rate that it is meaningful.
