Hey, what does sme and fsm mean please? (Where I'm from that's small to medium enterprises and free school meals but obviously not in ai and coding )well, the approach they chosen is very old, does not scale, gets complicated very quickly, it was used in 00s. It will be very hard to implement competent ai with it. Also with this approach ai will get stuck and do pretty stupid things easier to build from scratch, simply speaking it is not able to adapt to player actions. And FSM approach they choosen is not favored by devs, as it is not interesting work.
