It's only an issue if you keep multiple games installed of this sort of size. I tend to complete one game, then uninstall it. Mostly out of the sheer disgust after discovering how much crap most games clutter your drive up with. Background launchers, game data files not only in your user docs Saved Games folder, but also multiple other locations inc the root of your user docs library, AppData folder, Local folder, Roaming folder, Program Files.... The registry!
I've now refunded Far Cry 6, it ended up being too annoying for these and other reasons. Even though it's Steam, it will stealth install Ubisoft launcher and that runs in the background
