Super Mario Bros. 3 was $49.99 when it was released in 1990. $49.99 in 1990 has the same buying power as $91.13 does in 2014.
Atari 2600 carts were selling for $19.99 when the system was released in 1977. These carts held 4K of information and were usually designed and programmed by one or two people. Games for the Xbox 360 have entire teams working on them and can take up 6 GB of space. $19.99 in 1977 has the same buying power as $78.59 in 2014.
Why do you think that games should be cheaper than one of their lowest prices in the history of gaming? It's insane to think that $60 is too high of a price, especially if you've been gaming for any stretch of time.
