funnily enough, there was an infamous bug in GTA5 for a long time that was related to using JSON : https://nee.lv/2021/02/28/How-I-cut-GTA-Online-loading-times...

Putting the (very valid) reasons for not having human-readable game saves aside, are you sure it's worse than using a 3rd party library that's built to accept semi-valid input values, possibly evaluates user input in some way and has difficult to debug bugs that occur only under certain inputs? I agree that writing a stable and safe parser for a binary data file isn't easy, but there's less things that can go wrong when you can hardcode it to reject any remotely suspicious input. Third party XML/JSON libraries OTOH try to interpret as much as possible, even when the values are bogus. Also no need to deal with different text encoding bugs, line endings...

After finishing the article I immediately did ctrl+f "rust" and was disappointed to not see any of the results I wanted, but actually this comment is more hilarious than anyone saying "why didnt rockstar use rust in 2004!!!1111!!???" it's a bit more of a sophisticated joke since there's an IYKYK factor but it is no less hilarious. Bravo sir, bravo.

Telling a 3d engine programmer not to have opinions on data formats? Good luck with that.

To u/db48x whose post got flagged and doesn't reappear despite me vouching for it as I think they have a point (at least for modern games): GTA San Andreas was released in 2004. Back then, YAML was in its infancy (2001) and JSON was only standardized informally in 2006, and XML wasn't something widely used outside of the Java world.

On top of that, the hardware requirements (256MB of system RAM, and the PlayStation 2 only had 32MB) made it enough of a challenge to get the game running at all. Throwing in a heavyweight parsing library for either of these three languages was out of the question.
