the mega mod, is the best there is at the moment. if something is needed its a more stabile platform. it is an old game by now - and have a tendency to crash, because the game isnt up to date, or get serviced anymore. it could use some love. and more production chains

I see that there are a fair bit of workshop items and want to create a mod that changes the gameplay more so than the look of the game itself. Are there any good resources for doing this to help me get started on my way?

The gameplay can't be changed in any meaningful way because the AI can't be modded to do anymore than it already does or to do it differently, the engine doesn't support building animations, etc. That's why all the mods are just better buildings models and added production chains. Those mods do add gameplay value and some of them are really well done, but at the end of the day it's just more of the same.
