If a Game has Copy Protection I would prefer not to Buy it, but its good to have Copy Protection on your Games to Stop Casual Copying.
But everyone should have the Write to make a Backup Copy & they should not Try to make Copy Protected Games that are impossible to Copy. Also you should not need to use other Applications to make a Copy work eg DaimonTools.
They should explain to to the Purchaser on how they can make a Backup of there copy, or place a Card Explaining how to in the Box, after all there not Cheap to buy...
I wonder how they would go if you had to Contact the Game Maker to get your Retail Key that you just Bought at the Shop ? Meaning every Key that would get sent to the Buyer's would be on Record & if that Key gets Black listed then they would no who gave the Key out because it would be on Record... I guess you can call it Registering your Game in a Different way.
