Piracy not a problem huh...?

I would like to make note that most of those games were not even released last year but they are still being pirated. Also besides Spore being pirated horribly...Fallout 3, Far Cry 2, and Pro Evo which only released for less then 2-3 months made the 10 ten most pirated games of 2008.(side note the list was made as of dec 4)
Im not saying thats the only reason why but it could be one of them. Another reason could be the fact of having to make it for another system. Its a lot harder to port to 6 systems then 4(random numbers).
