Doomsday Machine
That's the most unclever of a sorry excuse i've seen so far.
It seems you fall into the same category. So let me give you a task. Civ 5 features base terrain that can have up to 2 total value of food and production. Everyhing else is treated as "terrain feature".
You are tasked on creating various types of terrain that give distinctive look on 3 continents. Base values are 2F, 1F1P and 2P and should make the bulk of the terrain.
Here are the "Firaxis" terrain values and names:
0F 0P desert, ice
1F 0P tundra
0F 1P -vacant-
1F 1P plains
2F 0P grassland
0F 2P hills
Lets see what you'll come up with.
