[citation][nom]fracture[/nom]If it's for the previous owner's DLC and such, then I still don't get it. For EA to know that the previous owner has a certain game and it's DLC they would have to register the games. What if it was never registered?And wouldn't it be better if people bought the used game and then when they want the DLC's they'll just go buy it at its full price rather than at 10 bucks for all of the previous owners' dlc.[/citation]
Well, knowing what DLC was used was easy; since each CD has a unique serial number/CD key, and EA keeps digital tabs on their customers anyway, they'd just simply look up that CD key in their database. With the way DLC works, basically a game is AUTOMATICALLY registered if you get DLC for it; after all, that's how (even with EA!) you can re-download the DLC should it get corrupted or such.
As far as marketing, of course EA would make more money per transaction if people paid full-price for all the DLC, rather than a $10US bargain price. However, the number of sales will be fewer.
I can actually understand, and perhaps agree with, EA's logic here: people who buy games used rather than new don't like to spend as much money on games. Hence, if they shelled out, say, only $20US to get a used copy of Dragon Age, they likely won't be too keen to cough up $30-50US to download a fresh copy of the Awakening expansion pack to go with it. However, EA seems to figure that if they were to offer it at a discount price of $10US, enough more people would bite to more than make up the difference.
Aside from the potential downside of confusion caused by people not knowing what DLC they might be able to get when they buy the used disc, I could see this possibly SLIGHTLY denting new game sales, while improving used game sales. However, since it'll cost EA virtually nothing to sell DLC, it could work out for them in the end.
