That was also my first guess, and it makes me quite annoyed at his claim that "no other game that he is aware of does it this way", because I'm fairly certain that there are plenty of situations where closed-form particles are also the more performant option.
As the same time, to be fair, plenty of people do not realize closed form formulas are the best approach here. I'd say that requires a level of intuition for the physics and maths involved that is not strictly necessary to make functioning particles the "regular" way.
Anyway, to switch the topic to something more fun: do you think one could make Age of Empires 1 and 2 perfectly rewindable?
