More on the reselling used games topic - IT business is becoming more and more service-oriented, and the same tendency is visible in gaming industry. Sony acquiring GAIKAI, NVIDIA presenting lines of server components designed to deliver streaming gaming, and I bet new offering from Microsoft (I hesitate to call this "console" as I bet it would be platform+services+box) would include something similar.
Game become a service.
Being a PC gamer, and buying most of my games via Steam, it seems to me the most natural thing that I am buying a right to use a service called "game". The terms on which a game is licensed to me + the price + the experience makes the overall offering which is appealing to me (then I am paying the license fee), or not (then I wait till the next round of Steam sales ;-)).
Disadvantage of not being able to resell the game seems to be counterbalanced by the lower price (usually PC games are much cheaper compared to the console versions), and most of the time it is fine for me. It saves me the hassle of auctioning the DVD, and posting it afterwards.
Seems that at the moment, in this area console market is still in the 20'th century ;-)
