Who knows but you people are focusing on the wrong thing.
Oh no, it's you who is focusing on the wrong thing. He went in there with a pre-determined opinion. No matter what they said to him, he was going to bash them. The guy tried to save him $5. He tried to help out a consumer get the same gaming experience without paying more. This developer comes off like an entitled douchebag. Your company already made money when GameStop purchased the game from you at the wholesale price. What they sell it for after that is none of his concern. He's being a whiny little entitled bitch. I know it, Gamestop knows it, he knows it, and you know it.
I imagine that's easier said than done when the platform you develop for let's it be free reign on used games.
Guess what? Not everyone wants to go buy a brand new copy on the first week a game is released. If I can buy the same game for $54.99 that someone else paid $59.99 for, I'm going to do it. I'm about getting what I want, for cheaper. Why should I pay $5 extra for the exact same thing?
Let me ask you this, if you go out to dinner with your lady or whomever, and you order a steak. They tell you that you can order one steak that's $25 or another that's $20 and there is no difference between the two. Same size, same cut, brought in at the same time, and so on and such. The only difference is the price, are you really going to pay more? Absolutely not.
