I remember a report in a games magazine about 5-6 months ago. It checked out every single large game only stores to find out about used games. Every single one claimed they'd be out of business if they got rid of used games and they make 70% of their profits off it. So they will NEVER willingly get rid of them. or want to lose that profit.
It's up to the developers. Not by going "Give us money or else!" but by making people WANT to keep there games. I've kept GTA4 and Fallout 3 because of the DLC. Same with Burnout, same with Dawn of War 2. These days a game really can't be a basic 6-8 hours, single player only type of affair because they AREN'T worth $60(or $100 here).
A game either needs a good lengthy single player, great multiplayer, high level of replayability or some nice looking DLC coming out for it(and not just a new map or two). Hell, even try what Gears 2 did and add a download code for some extra maps that you won't be able to get in a used copy. If developers can't do that, then expect people to trade in your games or just rent them.
Also, it always seems this is basically how a Jaffe conversion goes.
Jaffe: I think blah blah blah
Other: I disagree because of X
Jaffe: You're wrong because of Y
Other: I still disagree.
Jaffe: Well when you grow some balls you might understand dickweed
Other: Whatever, I still disagree because of Z
Jaffe: You're a mistake, not about your option but the fact you were born. My rubber broke while I fucked you mum.
Other: Fuck you. You're opinion is stupid and you don't seem to understand mine.
Jaffe: Grow up cactus dick, I'm right, you're wrong. End of discussion.
