I think we need to stop calling it "piracy". The only folks in the game-cracking and file-sharing "underground" I would call "pirates" are the folks who acquire source materials (sometimes pre-release) and actually "crack" the DRM. Then there are the less adventurous who acquire such cracked versions and host them on a fileshare. Still "risky", I guess, but not a lot of effort involved really. Then there are the majority of so-called "pirates"; the people who download such cracked versions for use. I think "crackers", "hosts", and "users" are better labels. Strangely, that almost fits pretty well with illicit drug markets...
I think pro-"crack/host/use" folks are either unfamiliar with the concept of value, or simply choose to ignore it.
We don't value anything by only the cost of raw materials. Aside from maybe the raw materials, but even then there's the cost of harvesting such materials. Yes, with digital distribution, you aren't stealing a physical CD, but only about $0.25 of a $20.00 CD or DVD is the actual cost of materials. Yes, the "you wouldn't steal a car" argument doesn't make a lot of sense at face value, but there's some merit to the argument "You wouldn't take a car from a lot and only throw enough money to cover the scrap metal value at the dealer". Though comparisons like that would be hard to convey in a 5-30 second PSA. Does anyone actually bring raw materials to their employer to earn their wage? What if you worked all day and your employer didn't pay you? They didn't take anything physically from you.
The ever popular strawman counter-argument "Illegal Copy != Lost Sale". True enough, I suppose, if you weren't going to pay for it in the first place, the developer wouldn't get any money. If you wanted the game, but didn't have the money, or didn't want to spend that much money, you wouldn't buy it. That is how the market works. You weigh pros and cons and make your choice as a consumer. If you would never have paid for it, you are implying that you ascribe no value to it. If it has no value to you, you wouldn't even download it. By offering a "free" option, file-sharing violates the product's right to compete. That has been the point of copyright law for the past two centuries in the United States at least.
As for other countries; they don't have a "right" to these games. Be it their median income, standard of living, government restrictions, or developer choice, if they can't get the game, they can't get the game. I can't afford a PS3, that doesn't give me a right to take one. Certain fireworks are illegal in Spokane City limits; that doesn't give me the right to import them and fire them off anyway, let alone steal them from some guy in Moscow, ID. The Subways here stopped carrying pepper jack cheese for a while. I could still buy it somewhere else and put it on afterwards, that doesn't mean I have to steal it.
There are a lot of unethical, illegal, and downright sick things that are the "norm" in many places: illicit drugs, weapons trade, child labor, nose-picking, adultery, burning electronics waste, fish-farming... Illegally copied games are far from the worst, of course, and actually quite petty in perspective, but are still an issue nonetheless. To excuse it by saying "that's the norm there" I suppose is fine if you are truly amoral or a moral relativist; just don't complain about Wal-Mart selling fish that have been farmed such that they destroy the local ecosystems in central America, or about Nike off-shore outsourcing to child labor sweatshops, or local "recycling" companies sending electronics off to China to have families and children burn CRT monitors to melt out the "useful" scrap from them.
It's just how things are done over there and don't you dare apply your arbitrary "magical" standards to it.
