Good move Microsoft - destroy the market that has kept the current generation going for so long.
Good move, encourage anyone who can't afford to pay full price everytime to crack their console and never pay for a game again.
Good move, make sure that every last ounce of revenue can be got from a system that isn't even out yet, on games that aren't even out yet, never mind pre-owned.
Good move, make the margin so insignificant on pre-owned games that you'd have to be a fucking moron to sell a game for what.... less than the retailer will make... less than 10%! - so if you pay $50 for a game, you can sell it for less than $5, which the retailer will then sell for $45, and hand most of that over to Microsoft.
Good move Microsoft - I think the PC gaming industry owes you one.
What I'd like to hear, is how this affects our statutory rights as consumers, and how Microsoft can somehow make the rules (laws) up as they go along, to benefit themselves and nobody else. I care about games, I have every major console - but frankly I'd rather fire up the GameCube than fire up the Microsoft branded lube.
