Should a game's physics be simulated or emulated? I had a fascinating discussion with a video game engineer about this very topic, and it reveals so much about the art of game development. ​On the surface, the two concepts sound similar, but they are worlds apart: ​▶️ Emulation is like a clever magic trick. It's about understanding an input (like a car hitting a wall) and creating a pre-designed, believable output. It’s efficient and light on system resources. ​⚙️ Simulation is like building a mini-universe. It applies the actual rules of physics to that same input, calculating a realistic outcome from scratch. It’s powerful and dynamic but incredibly demanding on performance. ​Here's the developer's dilemma: If emulation can be done so well that a gamer would never know the difference, is a resource-heavy simulation necessary? Should we build something complex just to flex our technical prowess, or should we use the simpler, more efficient method? ​The answer isn't...
