Comment $5 to $20 games exist now; IARC self-rating (Score 1) 37
Digital games themselves did not lower prices, despite them being marketed as doing so without the cost of materials/packaging/handling/shipping
From the summary: "Current prices are tied to retail. Without physical discs holding digital hostage we'll see a larger spectrum of pricing." As I understand this, paid downloads did not lower prices of AAA games because of retail price parity contracts. Paid downloads did, however, make the $5 to $20 tier for indie game pricing viable.
One thing not mentioned in the summary is that publishers of games distributed in physical copies owe a royalty to the age rating agency of each region in which a game is published. Publishers of downloadable games do not, instead relying on self-certification through the IARC form. The age rating agencies allow this because it's a lot more practical to update a game once it is found to have been misclassified.
