Wow. Truly that's bizarre.
Clearly the App Store was never meant for distribution of 75 GB games, it's clearly meant for mostly <~1 GB packages.
I'm surprised they even allow huge apps like that in the first place, and don't have e.g. a 5 GB hard limit for usability reasons. They should have a limit if they're not going to support patch upgrades.
Who the heck has 231 GB free on their Mac internal SSD? Almost nobody. Why would the developer even distribute this via the App Store at all, for such a miniscule user base?
Xcode used to be absolutely massive, being 10GB+ a few years back. They seemed to have done a better job at making it smaller.
