Okay, I'll bite.
Presented with the title of this topic I'm reminded of a - rather terrible - article on Gamespot about the next XBox. The article wasn't very precise and seemed like a lot of hearsay but among the things listed was the new XBox wouldn't play used games.
I'm not sure what that would exactly entail - again, the piece was completely short on details - but if it was implemented it would probably work a lot like how you have to buy online/multiplayer codes for used EA games only it would cost a lot more.
Anyway, if they (or any other company) were to try something so draconian I simply wouldn't buy that system. In Microsoft's case there hasn't been anything that's made me want one of their consoles yet so I'm not worried. What I am worried about the further along we get with games the further we get away from what's on the disc (hard copy) being the final product. I'm all for bug fixes but who's to say that today's DLC will be available tomorrow (outside re-releases w/the DLC.)
I understand the desire to make more profit, and I would usually endorse anything that undermines Gamestop, but I don't like making the second-hand market more intangible even though I kind of hate the second hand market. Too many people thrash the hell out of their stuff...
That said, I think that article was rubbish... but I like that it made me think about what it proposed.
