I present you a plugin that fills ALL requirements of RCI. This covers all the map so now you don't need to put 100 churches while making a realistic city.
There are 5 buildings which you can find them all in one category called "Sandbox", that is in the public category. The 5 buildings are a mage that covers almost everything, the health icon one covers health happiness, the education icon that covers the education happiness, the trash icon covers waste disposal happiness and the funeral icon covers body disposal happiness. You can also choose to be invisible if you don't want to be visible
(Note: this plugin is only for SANDBOX and FREE MODE, you can't build them in non sandbox/ free mode cities)
Warning: This plugin DISABLES achievements since it's an OP plugin. Disable the plugin if you want to get those achievements.
