Dear Sony,
On paper it might appear as though you are incentivising new game buyers. To me, however, you are calling buyers of used games (aka gamers) second class gamers that don't deserve the benefit of your full content. I'm sorry you lost $3.2 Billion this year, I know that's a LOT of money, but stop trying to milk every penny out of your fans and customers. That's why you've slowly been losing them for the past 10 years.
Do you know what people (and even many pirates) are willing to pay for? Convenience. Make your games easy to buy and play and ,yes, reinstall on a new machine and people just might return for more games.
