I do find it a little odd that someone who spends as much on sim racing gear as you have (based on your signature) would feel this way, but I fully support your right to be wrong! The best sim racing experiences will probably always be on PC, as it can be a niche market, so I don't understand why you wouldn't want the best/most software options to go with the expensive hardware.
I haven't upgraded my PC since I bought my 4090, although granted that was a big expense! As anyone knows who has a PC, the constant upgrade thing just isn't true unless you really want to stay on the bleeding edge. I probably upgrade my pc once per console generation, although I will fully agree that it's way more money than a console, but I also tend to do it in stages so the cost doesn't all hit at once and I use it way more than I would any console. My PC is more than capable of playing the latest games on a flat screen a couple of years after that upgrade, and I'll be skipping the current 50 series Nvidia cards so probably won't make any upgrades for a couple more years at least.
Because of game managers like Steam, most games are just turn on and go, with updates happening automatically in the same way as they do on console. I have Game Pass too, so I get to play a lot of the major releases as part of that.
Sim racing is probably the thing where I've had to spend most time tweaking, but that's down to using VR and to offset it, I then get to play AMS2, Le Mans Ultimate and a fully-modded Assetto Corsa, where I can drive pretty much any track and car from the last 100 years if I want to. On top of that you get cheap games and incredible stuff that'll never come to console like Noita, Stellaris and Battle Brothers (I could name way more here). VR support is streets ahead of consoles and I only play driving games in VR nowadays. Mods are optional, but of course they can be pretty awesome if done well and are something that's generally not available on console at all.
But added to all that, PCs aren't just for gaming. I use my PC:
- As a music and entertainment centre
- For recording and editing music
- For graphic design and video editing for my musical projects
- For streaming services like Rally.TV
I have a PS5 as well, I haven't turned it on since I finished The Last of Us 2 😅
