And there are ways to cast your Steam games to your TV and play them with a controller there, although I'd still suggest doing it through a wired ethernet connexion.
What I'm saying is, you have a PC, you can get a Steam account and look at easy to run games. There are so many. Also Good Old Games (gog.com) has a huge repertoire of games from the past decades that can also now be run rather easily on new machines. You can buy them and they make sure they run without problems on most machines. They cost very little, especially during sales.
PC is just a platform that keeps existing. With online distribution now, you have an account and access to infinite games that won't become unplayable because your console is broken or stashed in the garage. I can still play the PC games I played in 1996 if I want, on my current machine.
