Since this is clearly not going to happen, each disc must then only install for a single owner.<br/><br/>Microsoft did say that if a disc was used with a second account, that owner would be given the option to pay a fee and install the game from the disc, which would then mean that the new account would also own the game and could play it without the disc.<br/><br/>But what if a second person simply wanted to put the disc in and play the game without installing – and without paying extra? In other words, what happens to our traditional concept of a “used game”? This is a question for which Microsoft did not yet have an answer, and is surely something that game buyers (as well as renters and lenders) will want to know.</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>from Wired interview with microsoft.
