Figure MS and Sony don't make a dime on used games, so can't blame them from a business perspective on trying to figure out how to make the most profit. Not that I'd be happy with it, but makes some sense from business.SNIP
BUT....bear with me and think a bit abstractly here. How many used xbox/360 games are out there? How many of those are xbox live compatible? Now here is where your comment loses some of its backing. I know many people who don't or did not have xbox live....UNTIL they wound up buying something USED on the xbox 360 and they liked it so much they went to XBL. I know its probably a small market in this sense but in this case MS does get a trickle down version of a "used game" market sale.
