All these lame excuses for piracy- it costs too much, it has DRM, it doesn't have all the features that someone wanted, etc....
Steam, Impulse,D2D, already offer great deals throughout the year but maybe steam should try a "rental" system like others have said. Then I wonder what the new excuse will be for pirating games.
Like I said, the PC platform is just completely insecure. Pirating on it costs you no extra money, no mod chips, no money on blank media, and your system won't get banned for using pirated games.
Pirating is just so easy, maybe easier than buying the game, and it's free. You add those up together and you have the perfect recipe for pirate cake.
