Zero.

Steam doesn’t require any terminal opening, the hard part are shitty Windows games that pop up boxes to install extra stuff because for some reason they can’t install it when you install the game.

I mainly play indie titles, but actually zero times so far. Steam really does everything for you nowadays

Zero. Everything is done though Steam.

I said not much trouble, not no trouble, but that being said, zero times. Issues I’ve encountered have not been related to getting a game running.
