What encapsulation exists in OOP or procedural code, but not in functions and modules?

The complexity in games is peanuts compared to any random business UI logic at whatever random company. Managing this complexity is an explicit reason to use functional paradigms. If OOP were better at managing complexity, why has everything been shifting from OOP to functional paradigms?

What about the functional approach makes it inferior at state management in your mind?

Nah, I'm not gonna write an essay just for some random dude on the internet. Try writing a game. Like a real one, not tic-tac-toe. You'll learn quickly enough.

An Entity Component System is literally the functional approach to programming under a different name and with mutation by default. There’s even been a huge move toward keeping ECS data classes separate from behaviors. At that point, it’s just a less ergonomic functional approach with better performance due to lower-level languages (though ATS or Rust are just as fast as C).

Maybe you’re thinking of FRP (functional reactive programming), but that isn’t even super mainstream among most functional programmers. I know some small games have used it, but it’s mostly used for specific kinds of UI in languages that enforce immutability and no side effects.
