Warning: Spoilers inside! Source Remember folks: Downloads don't equate to sales. Us pirates are collectors and since the games are free we will download an awful lot of them. If we did not have access to this then we would still buy games but we would not buy in the same volumes that we download. Also this doesn't take into account some people who try before they buy, only buying if they feel the game is worth it. It also doesn't take into account people who are trying to find out which game is best (for example a sudoku game).
