world/

This folder is meant as a miscellaneous folder for all that other stuff related to the game. Code which are not commands or typeclasses go here, like custom economy systems, combat code, batch-files etc.

You can restructure and even rename this folder as best fits your sense of organisation. Just remember that if you add new sub directories, you must add (optionally empty) __init__.py files in them for Python to be able to find the modules within.
