Google, have you ever heard of that?

Hi Akira. I'm wondering how you learned to mod cities skylines?
I'm interested in creating a little mod that ignores unhappiness but don't know where to find the required classes to edit

Please update: Employ Overeducated Workers
Thanks :)

AKIRA: THANKS SO MUCH FOR both your ENHANCED HEARSES and ENHANCED GARBAGE TRUCKS mods. They are saving my city. They work wonderfully - no problems at all with anything mentioned by the "whiners".
Course, now I REALLY notice how badly managed my Ambulances and Firetrucks are. Is there any possibility that you will be putting out an enhanced version of those soon?
And what is a "district". Is it a "zoned" area?
Again, THANKS SO MUCH
