Gears of War 2 came with a one off code to unlock 5 additional maps and now WiiSpeak comes with a one off code to install the application. Is this future? Games will come with some sort of code that only works once to stop the pre-owned market. The pre-owned market is a very profitable segment of the industry, so much so that HMV has started a pre-owned section in their stores and their are also stores devoted to pre-owned games. On the other hand its revenue that is lost to the developers (well publishers in most cases), should they be entitled to that money.
