Federal laws allow you to return video games for your money back!
How many times have we had games that did not deliver on promised features? Horrible servers, glitches that not only freeze, but break your console, or games that have horrible game breaking lag. Some of these games never even get a proper patch that fixes the issues. Any other product on the market would be returned immediately for lesser offenses.
If I can't return it for my money back then I deserve the right to sell it to someone who might not be bothered by whatever glitch, or broken server issue the game has.
