Yep, they have pretty much managed to kill the second hand games market.
The real downside to me, is that in the past if you bought a game and it did not really do it for you, it could always be sold, and at least recoup some of the money spent .
These days I am very cautious about what I buy, slightest thought it may not be 100% for what I'm looking for, I don't buy. Simple as that.
