Re: @M Gale
There are more reasons. If I understand the console market correctly, the console makers sell their products pretty underpriced, because they expect to get sales from the sales of games.
Then they can budget for it. They managed to make enough profit when second hand games were completely unrestricted, no? If Microsoft weren't making money from the Xbox, they wouldn't do it.
Secondly, I don't think reselling games is very healthy for the whole business... The only one profiting from that are currently the resellers - parasites.
Game traders are not parasites. They provide a useful service to the end customer, that of being able to get rid of property you no longer want, and optionally trade it in against something new. In the case of a store like CeX, that new thing might not even be a video game. If it were not beneficial to the end user, they wouldn't be able to make a business from it.
Also, by selling their pre-owned games at a lower (or much lower) price point than the new games, they enable those without much money to get into games and series that they couldn't otherwise afford to experience, which then encourages future purchasing. Now, let's think of a demographic that are very keen on video games, but might not be initially able to afford them new....hmmmmm......oh, right - kids!
From publisher's and developer's point of you, it's the same if you just pirate the game, is it not?
It absolutely is not, and your thinking is flawed to the point of insult. A pirate takes a copy of the game without payment, and if they hand it on, they do so again without payment (generally speaking).
In order for a pre-owned game to be sold, it had to be bought in the first place. Every pre-owned game on a store shelf represents a new purchase. And many of those games that are traded in are traded in order to be able to afford, get this, NEW GAMES!
The second hand market directly benefits the game industry, but the arrogance and greed of major publishers, coupled with folks who would dare equate reselling with theft, is leading to this exclusionary system that will either make video gaming the pasttime of the wealthy few, or crash the industry entirely, as it so thoroughly deserves.
