Okay, let me tell you about conversion. Lets compare a brand new 60 dollar game to a brand new 20,000 car. Standard prices for goods and services. Now there is a standard amount of content held in a video game and a car. Last gen games were 6.5 gigs (roughly) and that was the amount of content involved in the game. Cars are different as some features are optional and the price is adjusted because of it features. But dealers still charge a certain amount compared to the content of the car. Now Imagine parts if of the game were locked so that only those who payed extra could gain access. The content is there, you just can't use it yet. This is comparable to a car dealer locking your truck, radio or other such thing, that only he can unlock for a price. Except, the car dealer would be losing a bit because of the cost of the things that were made for the car that you don't buy. A video game developer only needs to make that content once, and can continually profit from that content. But most game developers and and car dealers wouldn't do this. Because it is a dirty move by game developers and a potential profit lose for car dealers.
