There's a discussion in the forums that games are too expensive, and this great article at Avault might help explain why prices have risen through the years. They begin right from early consoles like the humble Atari 2600, right to the consoles and PCs of the present time, and conclude that price of games are pretty reasonable considering inflation.
"the cost of games is more a result of history and tradition than it is a consequence of capitalistic forces. Indeed, the $50 ($91 AUS) ceiling that many modern gamers take for granted was well established over a decade ago. If costs had kept pace with the rate of inflation, a title that sold for that price in 1989 would sell for nearly $75 ($128 AUS) today."
A very long and interesting article, definately worth a read.
