Hi, I am working on a paper examining attention currencies in gaming ecosystems, with a focus on attention as a mediating currency between real and virtual gaming currencies. I was looking through material by Goldhaber and Davenport and was wondering if there was any material examining these concepts and their application in gaming ecosystems particularly MMORPGs and perhaps even something on Goldfarming - already looked through Dibbell, Nakamura, Consalvo and Castronova in this regard. Are you aware of any work/research being done in this area around MMORPGs? or around gaming ecosystems that examine virtual economies in relation to the time, labor, production, and investment in MMORPGs? I was looking for a copy of "Online Game Interactivity Theory" by Markus F, its out of stock in India and would be too expensive to order. Does someone have an Ebook version of this book? I would really appreciate it if you could kindly mail me the same. Any other suggestions or advice would be very helpful Thanks in advance Best Arun Menon arun.kid86@gmail.com twitter : @arunuik
