Piracy gives you a better user experience than paying for games. Take steam - you have to run a proprietary application to launch your games, which can take these games away at any time, can modify your games to remove copyrighted music, leave them in unplayable states etc. Not to mention the performance impact from DRM, and the constant badgering about accounts/updates/logins/restrictions.
With piracy, everything is seamless. Go to your trusty repacker, click download, click install, and now you have a game that you cna enjoy for the rest of your life.
