I have some friends in game dev who have shipped some pretty big titles (and still do). They have very similar sentiments with regards to constant self-inflicted breakages and (lack of) testing and code reviews as well.

It’s given me an appreciation for the kind of code quality everybody just naturally agreed on and did back when I worked at a FAANG. Nobody needed to be convinced to write/maintain tests for their change, or be told to keep the mainline branch building cleanly.

I wonder if any of the large studios out there today have a culture of testing and reviews?
