actually its not really sonys fault-- they have to pay some to give us this stuff free
its well known that americans are deal hunters--- we will buy games a year later on the cheap--- its what we do
whil;e in europe if they want it they buy it-- old games dont really sell well at all-- so companies sell the rights to the games for less in european nations-- knowing it has reached end of life cycle anyway. and here in the states life cycle is basicly triple what it is over there,
and thats why you see such a huge dispat\rity in games
As an EU user, we get this exact same question as well. Usually it's 'Why does the US get better stuff than us?', or similar.
The usual answers we are given are similar to those above - licencing reasons, which is fair enough, and localisation, (which sometimes seems strange when it's related to content such as avatars the US have previously been given).
Mostly it's licencing issues as many games have different publishers for different regions and getting all the legal jiggery-pokery watertight can be horrendous.
Europeans are canny deal-hunters as well, sometimes more so, especially in the UK where taxation and generally higher prices make us folks seem to feel more than normally ripped-off, hence the healthy pre-owned market - and the sudden proliferation of those beloved online passes!
