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.
JSON didn't save them: This is the same studio that handrolled a JSON parser with accidentally quadratic time complexity, making most players wait 3 to 10 minutes to load GTA Online, for 7 years, until a player got tired and found the root cause.

You’re not entirely wrong, but a library doesn’t have to be “heavyweight” in order to be bulletproof. And you can load the library during startup and then unload it after; it doesn’t have to stick around for the whole run time of the game. Modern OSes will reclaim the pages after you stop using them, if there is memory pressure. Of course the PS2 didn’t do that I am sure.
Why weren't binary files used like I would expect in the 1990's DOS game? fread into a struct and all that
XML was everywhere.
Wow I had no idea YAML was that old. I always thought it was created some time around when CI/CD became popular. Now I'm really curious how it ended up as a superset of JSON.
Vouching seems to be time-lagged and require more than one.
The flaw isn't the language. The issue is a 0.5x programmer not knowing to avoid sscanf() and failing to default and validate the results. This could be handled competently with strtok() parsing the lines without needing a more complicated file format.
The comment reappeared, and while you're right about using proper libraries to handle data, it doesn't excuse the "undefined behavior (uninitialized local variables)" that I still see all the time despite all the warning and error flags that can be fed to the compiler.
Most of the time, the programmers who do this do not follow the simple rule that Stroustrup said which is to define or initialize a variable where you declare it (i.e. declare it before using it), and which would solve a lot of bugs in C++.
