The vs. 90's thing is an apples-to-oranges comparison. Floppies & hard roms vs. online distribution.
Start by understanding what compartmentalizing distribution does to prices- i.e. Microsoft/Sony/Nintendo certification, Origin/Steam, etc.
What I'm seeing is console certification driving up prices and then publishers using that as an excuse to raise the SRPs for PC titles.
I'm also seeing prices stay higher, longer because digital distribution is eating into the used game market.
I'm worried that as publishers each develop their own DRM/distribution software that competition will be further eroded.
Publishers are learning to act like governments because they perceive that consumers are learning to do the same- rule making, "legitimized" theft, surveillance, etc.
Sucks to be us.
