This idea is partially inspired by SimCity. The basic notion of this idea is that your nation is organized by tiles.

1 Tile "cost" 10 infrastructure and 20 units of land, in the initial idea, it will most likely change. For every 10 levels of infrastructure and 20 miles of land you unlock 1 Tile.

Tiles are used to designate zones and buildings. There are industrial zones, agrarian zones, commercial zones, and residential zones. Zones are initially free.

Agrarian zones reduce infrastructure costs by 0.01%. Reduces environment by 0.001.

Industrial zones reduce technology costs by 0.1%. There must be twice as much agrarian zone as industrial zones. You cannot exceed the 2:1 Agrarian:Industrial ratio. You must also have factories relative to the amount of industrial zone you wish to have. One factory = 100 Industrial Tiles. Therefore you cannot have more than 500 industrial tiles. Each industrial zone reduces environment by 0.01.

Commercial zones increase citizen income by $0.01 per tile. One bank = 100 Commercial Tiles.

Each residential tile provides 10 citizens with no impact to population density. It does however, affect improvement purchases.

Improvements now cost 100 infrastructure rather than 1,000 citizens. They cost 1 tile and perform their designated task.

Great Wonders cost 4-10 tiles based upon the scope of their role, and they perform their designated tasks.

There are also null tiles which are so when they are purchased but not being used, or war has stripped you of being able to use them.
