A pc gta iv special edition would be cool, like the one released for the consoles.
About the piracy stuff... it's a tough one. Hopefully people will think before clicking on that "download" button. It really hurts the industry and specially the gamer in the end. I mean, look at some of those game out there and the types of copy protection they use. Some of them don't even allow the gamer to play the game purchased if they detect the slightest hint of "strange" computer software installed.
