I mean, technically every game can be free on PC. But overall anyone that has a gaming PC and a console will definitely be spending more on the PC, unless they are given PC parta for free or something.
The way I see it: PC has a high upfront cost with minimal maintenance/upgrade cost to continue using it with newer releases for years.
Consoles have a cheaper upfront cost but no maintenance/upgrade. Once it’s obsolete (as determined by the industry, not the owner) then you are forced to buy a new console for new releases.
For me, in practice, I know for a fact that I have spent less on my PC components and games than I would if I wanted the same experience on a console.
