Balancing is NOT a goal of this mod, FUN is.  

When I am finished with my first series, I will also upload a 
"How-To" that will demonstrate the steps I took. I am sure it

You may use this mod as a base for your own work! 
Pay attention to file structure, ask questions if you need.
Don't forget to credit me. This mod was made (as with my others
