It's quite hard to find older PC games.
When the price drops though it's a good thing.
When Pool of Radiance : Myth Drannor was released in 2001 I wanted it but it was $75 canadian. I then forgot about it but saw it 2 weeks ago at $20 canadian again, so I brought it back home.
I don't know about the console games section since I don't check them, here the PC games selection is still quite big.
