For a long time (but not anymore) I was exclusively couch PC
Had this for any setup but this thing I used maybe once every 6 months, if even that
Windows would immediately prioritize booting Steam (a small setup to do right) and go into big screen. I would not even catch a glimpse of the desktop after the login.
Had an Xbox controller AND a Steam controller for anything that would use more a mouse. I played cRPGs that didn't support Xbox controllers on Steam controller. Torment Tides Of numenara & Pillars of Eternity comes to mind.
Also bought a small app which I wouldn't recall the name that made the controller act as a mouse everywhere even outside of games and on the desktop if I wanted to.
