Golden Age = VCS, O2, Intellivsion etc
Silver Age = NES, SMS, etc
Bronze Age = Genesis, SNES, etc
Where do we go from there? When the PSX and Saturn are 20-30 years old, do we come up with another precious metal since those systems will be considered "classic"? When does it end?
If we are going to use some kind of time stamp, does that mean the CD-I, Pippin, and FM Towns Marty become "classic" simply because time has passed?
