I'm not seeing a problem here. Every other industry that produces nonperishable goods deals in used sales: Cars. Houses. Bandsaws. Clothing. Books. Appliances. Music. Computers. Sporting goods. Every last one of these manufacturers understands that there will be a used market for their products, and they won't see any of that profit. Somehow, they all manage to get by without some sort of industry-wide crisis. Video games are "different" somehow? We need to make sure the developers get a cut out of every transaction that takes place? Why? No one else gets that. (Well, okay, the IRS does...)
Second, there are places to buy used games other than Gamestop. At these places, the sellers will usually get better returns, and the buyers will have a much better overall discount. Amazon, eBay, Craigslist, even Best Buy is getting in on the act. There's no reason to hold them in contempt for this. They aren't the only game in town, nor are they doing ANYTHING that hasn't been done since way before video games were invented.
The developer's problems, which they continue to keep quiet about in the face of all their histrionics, are their gigantic budgets and shorter product life cycles. They've pushed themselves to create very expensive games that only sell for a very short period of time, and in order to maintain that business model, they need to guarantee that every single title they make will sell a maximum number of copies and for a premium price. It's to the point now where every release needs to be a mega hit or it's considered a complete failure, and literally could ruin the company. This is a strategy that WILL end in disaster.
I'm sorry, I don't see the developer's point AT ALL.
I'm not saying there shouldn't be a used game market. There absolutely should be, but there needs to be a more fair market on games. You can buy a car, and yes it loses value once you drive it off the lot but you can still sell it for what it's worth later on. I think my orignal post was more in anger towards Gamestop than on the actual issue with developers my bad. I just feel that part of the problem with the whole modern industry is their fault. Of course like you say, people can buy from eBay, CL, etc, but I think the average person doesn't know any better.
