Re: Stop regulation
Most stores won't do it -because- WalMart won't.
I don't think you understand precisely how much power WalMart wields. If WalMart does it, most other stores do it too. WalMart has something like a a fifth or tenth or some other really high number of all business in the US. So what WalMart does, other people do.
That said, I can only think of one store that doesn't carry AO games (EBGames). I don't go into many others.
When WalMart changes its policy, other stores will too. The only way to get WalMart to change their policy would be to show that there is a significant market for AO games.
