Basic economics dictate what you should ultimately spend on anything is dictated by "opportunity cost". If I were on 80k salary, which works out to about $40 an hour, purchasing a $20-40 game/DVD legally is not a problem. It's "fair trade". Now, I'm only going to assume you/your family are fairly well off with this 80k assumption, but truth is, the national average is less than half that. So if you're in the mindset of "well I'll make this back in an hour", well, change that hour to two and a half. That's still not too bad. About a 1:1 ratio between the work/enjoyment.
Now, Argentinians aren't that bad off on the grander scheme of things, at about a fifth the salary. That would push the game to about $100-$200 range. Yeah, no thanks. Maybe Black Friday, once a year, or something. But even that's a stretch. That's a day's wages for most people.
And what about the Chinese? They're making 1/40 what we are. So at "retail" prices, that's equivalent to $800 - $1600, a MBP's worth. For a game/DVD. Yeah, **** it. So that's why "just buy from ebay for retail and have them ship it" is not really an option, is it?
And India? $1600-$3200. **** it.
