To Do List: FFXV, Dark Souls II, Monster Hunter, Fallout 76, COD: BO4, Sea of Thieves, Gears 5, and 40K: Inquisitor.
I reckon X for your first time, as going back technologically it's probably the easiest jump. But VII and VIII are great, and IX is my favourite.

Cool. I’ve only played XIII, XIII-2 and lightning returns. XIII was the only one I truly enjoyed.
I’ll get around to XV and 7 remake sooner or later.
