Yeah, Total War isn't for everybody. I do see what you mean though. I personally would love to have played the new God of War, Spider-man, or even Red Dead Redemption 2. But there's always going to be exclusivity, especially since a lot of these games are from first party studios. Definitely won't be any Nintendo games on another system.
There's always going to be an experience on PC that you won't get from elsewhere. Arma series comes to mind, but a bunch of franchises also started on PC like Call of Duty, Battlefield, Crysis (like you mentioned) Elder Scrolls series, Fallout, The Witcher, Doom, Quake, Grand Theft Auto, and Diablo just to name a handful. PC is a good platform to start franchises, so who knows, there just might be another Crysis exclusive PC game around the corner. PUBG was only on PC for a year before expanding.
So far, ever gen my routine is get new sony,Microsoft and Nintendo consoles and if lucky my PC doesn't bite the curve will still use this average pc which later will be the new potatato norm heh, but can still play games made for potato pc's that interest me like second life I guess XD? The only time i'll upgrade dramatically if steam had a for certain an graphically and demanding game that can't be ported to ps5 ever until ps6 that shames last of us 3 ps5 is when i'll upgrade my PC maybe the successor to 4 titans :).
I game on all consoles and PC
