Another point. Meteor cannot be everywhere on the overworld as in the OG, given that it’s presumably moving in a straight line towards a fixed point, namely Midgar. So I wonder how they bring that up to modern standards too. Although I SUPPOSE we don’t have enough info on Gaia’s rotational axis nor on whether Meteor is or isn’t circling the planet either ... I guess ...
Or maybe it was moving in a straight line and it was just a(n) (un)happy coincidence they were in the same place at the same time.
Regardless of which of these it happens to be, though, you're quite right that the rock shouldn't be visible from everywhere on the overworld at any given time. It should either always be visible from above Midgar or, at any given moment, visible along half of the latitude Midgar rests upon.
