There seem to be never ending mods. There crazy and bad that mix into our own world. We get idea from mods, movies, shows, and beyond.
Creating a working game mod is is never easy task that depend how long you want to build it or knowledge of how much you code to make it work.
There are always good and bad feed back on people talks from forum to forums. There are never ending talks.
Idea pop out people head and trying to recreate into a game that is workable. There are up and downs to making the game people really wanted to do. But some people never give up or trying some similar to get it working.
Creating ideas list then crossing off the list that does work and doesn't work with them. But testing them out are always fun and boring at the same.
Not all people have the same skills. That we are different not the same person to person.
Different engines can give different feedback in people good and bad building the mods. But there are never ending supplies in idea and people skills.
Hard part is that people have to work together to make a good mod. But there some who work and some who goes to to school to learn.
Do thing what you like to do until to try again. You have the skill even you don't. Learn it and if not try other. There is no right answers for building a mods until people how right idea how the game works.
Note: I am writing at night. Just got an idea.I have no idea until rewrite this again.
