Critical Gaming: Interactive History and Virtual Heritage (2015 edition) is in a Routledge campaign for May (2020), which allows anyone to register and get free access to the book (via this link) for 7 days. After this 7-day period, they can buy a copy for £10/$15! *Trust me this is a lot cheaper than before!

Is there a catch? I honestly don’t know but don’t think so!
Well, one catch might be Kortex catching you: you can only read the book inside their (free) app, no way to take it out. So now book sellers become private castle libraries again?
