I think this is a good idea. It's easy to dismiss people as being lazy, but remember that the people who buy games aren't necessarily "gamers". Parents, Little Billy, etc. may buy a used game thinking they are getting a good deal, when in fact they'll end up paying more than the new version if they want all of the content. This, of course, thanks to Gamestop's awesome $5 off new game price for a used game. Should it be a law? Should court time have been tied up with this? Of course not. You'd like to think companies would be honest and up front with thier customers. As we know, this isn't the case. Good move, IMO, and one that Gamestop and ANY retailer who sells used games should be doing.
