A regulation like this will probably do little more than scare the local shops into taking ESRB guidelines more seriously in their transactions. Pre-rated games will have to be grandfathered. No way in heck could one realistically enforce something like that on eBay or at CGE-type events. I don't have a problem with it at all if it works out that way.
And the last time I checked, nearly every serious effort to censor videogames in this country is initiated by a Congressional Democrat. Joe Lieberman, anybody?
Don't let's turn this into a flamewar now. You made your anti-Bush crack and I made a semi-informed retort. Let's just call it even.
