PC parts can be reused and resold until they're irrelevant. Decades old PC software can run on the latest hardware (often much better than it did on its original hardware).

Meanwhile, consoles do one job only, play games. If something breaks, more often than not you get an entirely new console; maybe the manufacturer actually fixes your old one (if they're still working on it).

They also lose security updates and become opportunities for botnets to infect and exploit. No device should be used past its end of software life that's connected to the Internet. Regardless of that, many people do continue to use old consoles and smart phones that are long past their socially responsible expiration date.

Beyond that, if someone has a computer capable of playing a game, to force them to buy a different piece of hardware is by definition unnecessary ewaste.
