Well, if this aspect is enough for the "exclusive tag" there are thousands of additional exclusives on PC.
All those "60-fps-exclusives", "100-fps-exclusives", "native-4K-exclusives", "mouse-exclusives", "ultra-widescreen-exclusives"... so all those multi-platform games with experiences we can have only on PC, far more impressive than the console versions.
In that sense they are exclusive to
$700 computer, $1000 computer, $1500 computer, $2800 computer, $4000 computer etc.
So while true you can have the unique experiences, it is obviously a price to pay.
