The year of peak might and magic

As a side (but arguably related) topic:

Is there any webpage or book or any media that analyzes the technical aspects of a game? Take HOMM3 as an example -- what are the most difficult technical problems and how did the developers solve them? What are the algorithms that run aspects of the game (e.g. how is path-finding implemented? How is AI implemented?)? What is the architecture of the engine? Does it have a scripting engine and if so how is it implemented?

I like post-mortems but mostly are given by designers, directors, not programmers -- and even by programmers they did not go very deep like "John Carmack" type deep. The "Black books" by Fabien came into mind but these are few and far between.

Check out "Game Programming Patterns" by Robert Nystrom and the GDC Vault for technical deep-dives. For HOMM specifically, the VCMI project (open-source HOMM3 engine) has source code that reveals implementation details like their A* pathfinding and combat AI systems.
