When you find the DLC on the original dvd of the game, that is how you know that it's cut content and that to me is deceptive, as for making up their own prices, Australia would like a word with you.
Again you are being disingenuous, even if you where to give out DLC for free, as you say it, it would still not be free content, because people payed for the main game. I am not saying I agree with this (that it should be given at no cost), but the sum amount of the DLCs prices should not equal or exceed the original price of the game.
Yeah, this has nothing to do with the prices rising, but it has everything to do with DLCs ending up costing the same as the original game, if sometimes not more. They could never have gotten away with something like that in an expansion.
