I remember there was an issue though with ME2 where GS employees didn't tell used game buyers about the Cerberus Network thing, and people got pissed off about it, so I doubt selling games at $50 $10 will work well for them. If they try to be sleazy and don't tell the consumers, they'll piss people off. If they do, the consumer will think "Hmm, I can pay $60 for a used game or $60 for a new game, easy choice". This is assuming a consumer wants the game when it is relatively new of course.
In the end though, I don't know if this idea will work. If it does, great, keep doing it. if it doesn't, they better drop it fast. Of course, what one can mean but 'if this idea will work' is totally relative anyways. Personally, I just think there should be some sort of law requiring retailers to give publishers a certain cut from used game sales. I think that would be the cleanest and fairest solution, but things don't usually work out so easily.
