Hey, I did my part by buying the game on day one.
Maybe the PS2 version will have better sales once they release it a little before GOW3 during the hype.
Anyways, it's a great game but really only lasted 4-5 hours at most, people know this, and that may have led to rentals or downloads. Either way, I quite sure this game WON'T have great legs since it's so easy to just download it.
@Galaki: Casual gamers don't know how to pirate games, nor do they buy PSPs. What does that tell you?
