its not really used games that create the problem its the prices for new games in first place....i mean it might be ok when game costs 60bucks in USA.....but hell when it costs 2100CZK here it means you have to pay 10% of average month salary(mind you more than 70% of people fall well short of average) for new game....nobody is going to pay that.....sure if it would cost say 1000CZK many more poeple would buy it...
also if the game was good enough most people wouldnt sell their copies....
