Lately, I've been browsing through several community members' blogs who were attempting to mod the game primarily by configuring from the game's base files. Then, I stumbled upon a blog post by Noddite that detailed how to make every city have all industries. Subsequently, I made sure that each city had available industries. Keep in mind that I still haven't managed to configure it in the special locations of the story mode or in the tribal zone because these locations weren't designed in the code to initiate new industries.

Here's a link to a Google Drive with the modded game file for those who want to try it out. Why am I uploading it to Google Drive? Mainly because I can't upload files larger than 10 MB to the website.
