A past coworker who worked on Cobalt[1] told me that they spent entirely too much time implementing stars in the sky of the game with some amount of real(ish) star system physics behind them.

I can understand people removing polish things like that if there are usability concerns, but those small things add up to a lot in an end product and are a joy to find and explore.
