In practice, for most classical RPGs you can get away with simulating each of your PCs and NPCs as a box (parallelepiped), or as prism (say, hexagonal or octagonal one)
Another Quote:
Mathematically speaking, without Interest Management, the amount of data on our servers will need to send (to all players combined), is O(N^2). Interest Management reduces this number to O(N)

For fast-paced games, there is one big problem with the flow shown on this diagram, and the name of the problem is “latency” (a.k.a. 'input lag')
Another Quote:
No, better bandwidth doesn't necessarily mean better latency

From the 50'000-feet point of view, 90% of the differences between modern mainstream programming languages (as they're normally used - or better to say, SHOULD be used - at application-level) are minor or superficial.

With 'callback pyramid' it is not easy to express the concept of 'wait for more than one thing to complete' , which leads to unnecessary sequencing, adding to latencies (which may or may not be a problem for your purposes, but still a thing to keep in mind).
Another Quote:
Don't even think of converting all of your code to a so-called Continuation-Passing-Style
