Sony is kind of ignoring the little fact that $60 is a tremendous amount of money to risk on a brand new game, for some people. Realistically it would take six weeks for me to be able to afford that and still have things like an emergency fund, food, rent, internet, electricity, bus fare, etc. That's if I didn't want to spend anything on any other luxury in that period. $30 or $20 is a lot more manageable.
Now, you'd think people like me wouldn't have game systems, except that we also have roommates, and those roommates have christmas bonuses, parents, grandparents, whatever, that they've used to get consoles. One way or another, poor people will find ways to entertain themselves
But this means that, in addition to sinking that wad into a game I may or may not even like (and which I can then probably no longer return), one of us is going to have to give access to an account to use it on. Or just keep our own games to ourselves, nyah nyah. No, most people are just going to use a single account per system, so that means that if I leave, I can't take my games with me.
I know I'm probably not their intended market or whatever, but it kind of ruins the whole system for shared households. It's not going to change the amount of money I can give them if they eliminate the used games market. I mean, unless they pay me to play, that'd be swell. Or slash price points, but why wouldn't they just do that to begin with? Just a guess, but I'm betting their sales aren't going to jump much if Gamestop and the like disappear. All that will happen is their brand will get less exposure, less interest, fewer games, collapse.
