I wish the author got more into the weeds of anitcheat and how it evolved over time. Jagex was banning bots based on mouse movement heuristics in like 2005. 20 years later and there's some JS framework on the front page here heralding that same kind of analysis as some revolutionary new approach. I can only imagine what the modern anticheat engine entails, especially in the era of LLMs that can reliably emulate a human player. (Some of them can even write quite technical blog posts that almost escape detection ;)

Ultima online released in 1997 and required only a 28k modem.
I also would argue it was a more complex game.

> Before any networking occurs, the client runs a breadth-first search using the local collision map to build a path from where you are to where you clicked, and then writes the packet for the server to read. [...] The packet contains the absolute position of the first waypoint in the path, followed by the delta of each waypoint in the path against the first one
How come the client sends waypoints rather than just the destination? Naively it seems like sending less data would be better. Is the pathfinding so expensive that you'd want to avoid doing it on the server? I suppose it works out as long as it's cheap to validate/correct the client's path?

Is this article just an analysis of the Lost City[0] codebase without linking Lost City?
