About This File
This is a single city region; 2 X 2 km, the same size that SC5 cities will be. Too many terrain features (such as hills/mountains and water) might prevent you (or if this wasn't a simulation of the new rules: a future neighbour) from building a large downtown core, so this city had to be limited to a river and a bit of texture. Please don't give a low ranking just because it's too small, or too flat.
Here is the challenge. When you are in terraforming mode, at the start of the game, you can add trees...and that is it. Build your city in mayor mode using no terraforming tools, height-changing cheats, or land (terrain) development mods. SC5 will be the first Sim City Game without terrain changing tools (random generation or otherwise). If you want to limit yourself by not using farms or subways or other confirmed Sim City 5 omissions, then go ahead.
[s]This is a zipped file, so you'll have to unzip it before using[/s]. Otherwise you would follow the default method of adding a greyscale map to your game: Create a folder (using whatever name you wish) in your Documents/SimCity 4/Regions folder and insert the greyscale [s]bmp[/s] jpeg and config bmp into your new folder. After starting the game, load your new region and render it (press Ctrl + Shift + Alt + R; then find the greyscale image you just inserted, highlight it and press okay) and viola, region created.
*Update: It works and it always did. Once rendered, you have to hover over the city and click start a new city.
