kdrnic's Caves of Qud beginner notes

The guide below I wrote mostly for myself as a "notebook" of info I found, but then slightly expanded it with stuff that may be useful to others.

As of finishing writing, I have 16 hours of CoQ playtime and have a level 20 character, definitelly still a beginner as well, perhaps a slightly seasoned beginner.

My previous roguelike experience included beating DCSS with a minotaur berserker and playing a good amount of POWDER on my celphone.

Justification

The game is a tad opaque. As this Qud denizen explains (I don't agree with his overall opinion):

Engine entities

This is a comparison of data structures for game entities (aka objects, actors...) across different games and game engines.

Game engine choices

  1. Source code has to be at least partly available, either in original form or through reverse-engineering or a remake
  2. The complexity of a 3D game makes those generally more interesting
  3. Similarly, a game in the action genre has more interesting architectural challenges than other genres - complex AI, several different object behaviours, all data structures must be highly performant, etc.
  4. The code is preferentially in the C/C++ languages
