Used games do a lot of things
Firstly they stop new games from being forever sold at $80 plus
Secondly they allow people to play games which have gone out of production (like PS2 games)
Thirdly they encourage people to buy games on release day by giving intensives to trade in and put that money towards the new game there by increasing the numbers who will buy release day (EB gives extra credit if you trade towards another in store product and even more credit if you trade towards a preorder) because not everyone could aford to buy every new release
fourthly the flip side of that is that it allows people who cant aford to buy new games to buy games and therefore increases the numbers who will buy a console in the first place and even increases the number of new game sales as very few people JUST buy used
Lastly it keeps EB in business because the margins for EB are NOT enough on new games and new consoles to keep the stores open and this gives competition to the consoles online stores, DEFINITELY a good thing. This allows people to access there consumer rights without having the issues that they do with online only (see the issues Apple have realizing that they are subject to the consumer laws too), this also directly competes with the online stores. Further more people may well factor in the resale price when they buy a product because they always intend to trade it back in so factor that value in when they decide if the price is worth it.
