Your gradient may be true to the general public, i don't know; but I can tell you that concerning myself and my brothers and immediate friends, it's not. We thoroughly examine a game before we make a purchase.
The only way we don't is if the purchase is cheaper than a rental. As far as buying games new, doesn't happen. And I think I'm speaking for a lot of people on this. New games are a risky buy unless you've played it at a friend house or etc. and you know that you want it. The industry is more like that now than ever before.
Basically I don't agree. I think people are realizing that many of the titles are just spam. Which makes sense because many of them are.
