This is a mod list for a group project, where everybody gets one (or more, depending how many or big I make them) island, and builds it to interact with the rest of the city.

We have a few mods that should be especially understood:

District Stats
Purely just UI, but it lets you know the water, electrical, sewage, garbage, etc.. usage and production within a district rather than the whole city. This is important because if someone's city is underproducing severely, the only solution is for others' to pick it up until it's your turn to play with your city.
This might not be too big a deal if people make their cities centralized, like one player's city is lots of nuclear and solar power, another is a lot of water pumps, etc..

DistrictRCI
This one has a bit more notable implications. In the vanilla game, demand for RCI (Residential, Commercial, Industrial/office) is city-wide. This mod however makes each district act more like an independant city. One district may have lots of residential demand, while another needs more commercial.

Traffic Manager: President Edition
This one you don't have to know, but it's very useful and will make complex roadways much easier, and is literally required to make a working Diverging Diamond Interchange, should you want that.

Ploppable RICO
RICO stands for Residential, Industrial, Commercial, Office.
In the vanilla game, RICO buildings can only be grown- you zone an area, and citizens build whatever they want. This allows you to be able to place some of those buildings. It's mostly used for other mods that are buildings you probably wouldn't want a dozen of, like the Data Mining Agency.
