Pirating>Buying used games
That is all
Not actually true.
While piracy has been shown to be negliagble when it comes to sales.
Used markets have been show to increase new sales and be a positive force in the market place.
I mean think about it... where did those used games come from?
People who bought the game new.... why did they buy the game new? Partially because they knew when they were done with it they could sell it and put that money towards new games.
