So I went to buy New Vegas on Steam http://store.steampowered.com/app/22380/ and it's listed for $89.95US.
Now, I'm an Australian so that comes out at $92AUD. I can walk in to the average store and buy the BOXED copy for $79AUD.
I guess my main point is that people who live in America can buy it for $49.99US on Steam, the EXACT same service I would get charged $89.95US for. It's not like there are overheads like shipping on this kind of service.
I hope that the developers get the same amount of profit for the game no matter what price the consumer pays because I am going to wait until it goes on special and get an American friend to gift it to me over Steam. Hopefully this way the greedy publishers who had no hand in my sale get as little as possible.
