Piracy or Used Games. Which one do you think hurts Developers more?

[SvennoJ]

"Even if we forget about the numbers that those two categories of people account for, it's wrong to assume that every person who purchased a used copy would have purchased the game at a full price."

And it is also wrong to assume that everyone that bought the game at full price would have done so if not for trade in credit of previously sold games, or for the ability to sell it on after finishing it.

At least money from a 2nd hand sale goes towards buying new games or consoles. Nobody ever sees any money from a pirated copy. (Well apart from pirates that sell bootleg dvd's or hdds loaded with games)
