Every single company that has tried to tackle a million planets to explore has failed miserably. Every single one, no matter how much time and money they had.
Fallout 4 in space was always the premise. I thought maybe they'd take this one chance to build a new engine but within ten seconds of the first gameplay trailer I saw it was like nope, that's the same jump animation from 2008 FO3
FO4 looking better and better the more people learn to hate Starfield. Game is going to be damn near ten years old and still their magnum opus.
