Because it is, it's not a title for an average Joe, it's a simulator, it's in the name even, it targets a specific group of people/enthusiasts, and once the visual impression wears off, once people check out how their hometowns look in the game etc. I really don't expect many XB players to stick with the title for longer, people who are really into this stuff have already been playing it for year on their PCs, with throttles, pedals, VR googles and what's not. Because really, there isn't much gameplay in it other than some sightseeing, the franchise is decades old now, for someone who wasn't into it already there won't be anything new in FS2020.
