I'm thinking about making something physics-based for this jam. However, physics simulations are rarely deterministic, and even if they were, are prone to butterfly effect (ie. small variation in start position will have great effect in end result). Is this interpreted as randomness? Judging by dice rolling example, it could be (as dice rolling is also deterministic, albeit hard to predict event).

Maybe another way to put this is: does emergent behaviour = rng?

Edit: I came up with another idea which is less ambiguous.
