Some people in Los Angeles have buy some games for 20$. This is because Amazon give discounts. Is all ok, but on the other side of the pacific, people play for the same game maybe 80$. Media in that part of the world are more expensive for not real reason. And I am talking about a digital download. I suppose the media cartel there can use higher prices, since physical good can be really more expensive, if are produced elsewhere and imported. But theres not good reason to apply that to bits. You can have a server in NZ and it will cost you more, but not all that much. The media cartel is overcharging NZ and aus guys by some orders of magnitude.
Another country that get cheap games is UK. You pay less, because traditionally the englishmen gamers are very picky about price and quality, and wait until a price is "fair". So USA pay less for games, UK pay less for games, and australia/nz that are also a english speaking country... pay way more.
Is even more rich, because Australia and USA have some trade agreements. So if you try to do this to a USA citizen, he could use the weight of his govern to screw you.
Combine that with a Internet that mostly suck. Digital citizens on that part of the world have a real problem. Digital enteirnament is way too expensive, Internet is slow and expensive. And now the MAFIAA make so abusive laws are approved. Well.. It has to suck to live in that part of the world :(
