I've been compiling a list of ways in which physical reality is similar to game engines or mechanical simulation in general. Here's my list so far:

- The observer effect, quantum entanglement and wavefunction collapse --> lazy evaluation

- Speed of light --> speed of causality to resolve the object interaction problem O(n^2)

- Quanta of energy, Planck's length --> discretization of reality to limit computational precision

- Unreasonable effectiveness of mathematics --> reality is implemented with mathematics

- Parsimonious physics --> simple physical rules are less computationally expensive to evaluate

- Entropy --> stability of the simulation and a guaranteed "wind down"
