In SimCity 4, you don't just build your city, you breathe life into it. With god-like powers, you sculpt mountains, gouge riverbeds, and seed forests to lay the groundwork for your creation. Then construct the most realistic metropolis you can imagine. Your city comes alive with the hustle and bustle of construction crews, the snarl of traffic and the activity of your Sims. Build mansions on mountainsides, cross canyons with bridges and raise skyscrapers downtown.
This map is,well a map. Actually first one i made. It has a lot of rivers and islands,hence the name. Perfect for your bridging projects. You also have a bunch of craters in the north part,it supposed be a ancient super-volcano.
looks nice, but is kinda flat towards the middle.
