matter is more than firepower
China is the flywheel the manufacturing

Actually you've touched on a critical point that I find is often not addressed in such wargame simulations, i.e. China's manufacturing prowess. I don't think it's particularly hard for China to churn out thousands of missiles and hundreds of thousands of drones / rockets continously if needed.

These simulations all seem to adopt a static view of things whereby they start off with the current inventory and then end with depletion.
