This is a simple MS Paint RTS type of thing. Build your own base with mining facilities,houses,an army, etc. I wonder how far this would go.
1. Don't start off with a huge civilization. Start small and grow.
2. DON'T FUCKING SAVE IT AS A .JPEG
3. Don't make something that will wipe out the entire land.
4. Have a little common sense.
5.Don't make invincible soldiers and bases.
You can make anything you please and build whatever you want. Just follow those rules.
The blue spots are lakes for a water source. If someone can make them better feel free to add detail.
