According to usinflationcalculator.com a launch PS3 would cost $936.88 in today's money. But...
Online was free.
It was fully backwards compatible.
The controller didn't break after 2 years.
It included a disk drive.
Exclusive games were actually exclusive.
Meanwhile a PS5 Pro is $779.98 once you add the cost of a disk drive. $79.99 a year for online. $75 for a new controller every two years. So after two years of PSN and a new controller it costs the same as the PS3. After four years it costs even more because you've bought another replacement controller and paid for PSN two more years. Ridiculous.
Modern.
Consoles.
Suck.
