Went for the Game Pass option as it's cheapest and will judge afterwards if I want to plump up money.
I've has a right time with trying to install this tonight. PC hasn't had windows updates in an age, which prevented Game Pass installing. Updated and BSOD all over the place. Reinstalled OS and then I was getting weird Xbox Game Pass crashes and then mfplat.dll missing errors. Sorted it by installing windows media pack.
Way too late now, so left it downloading the 91GB.
Am concerned how my 4470K, 16GB RAM and 980ti will run this at 4K, i'm going to have to drop the resolution, but I just hate running at non native resolutions. I can see it being a slideshow!
