For some reason on my client, it can’t remove the spoiler (gives a network error). I’m assuming it says that since the ball has more mass, it has a higher attraction rate of its own gravity to Earth’s, so does fall faster in a vacuum but so miniscule it would be hard to measure?
I can’t tell my hours, because I left it open while doing other stuff, and overnight etc. Same with Ark. Both have 8k+ hourly, but FFXIV has more (but isn’t in steam for me).
