I was working on a C code base with classes, inheritance, and polymorphism, all done by hands and macros.

Something like

typedef struct s_some_class {
    void (*method)(this *s_some_class);
} t_some_class;

Overall, learning C was the best enabler in my whole career. For instance I was learning Python by tinkering with CPython VM, so when I see these ‘WAT’ quircks I know exactly what’s up.

While working on Borderlands 3, the team was severely underpaid. People started quitting, so Randy promised them an “unprecedented company profit-sharing bonus model.” That never got paid—he blamed “higher-than-anticipated development costs and sales not meeting projections.” Borderlands 3 went GOTY, a few dozens millions copies sold. Randy secured a $12M executive bonus for himself. When staff expressed dissatisfaction, Pitchford told them they were free to quit. This was in the middle of the pandemic, and the job market was absolute crap.
