Yup. I’m running a 500 gig X1 still (waiting for Scorpio), and I filled the HD with that, AC Unity (which I think was in the 60-70 range), Fallout 4, Dead Rising with all Dlc, and GTAV. I know single layer Blu Ray discs hold 25 gigs (or 50 for dual layer), but it shows how much additional data is needed for patches…
