What I have
I plan to create an 'alternative timeline' for the earth, which means most of the earth's features are identical, the only major difference is, that humans appeared at another time, so although all continents are there, they have changed in shape and position a little. (a few 100000 years prior/subsequent to our current date)
On this world, two major powers fought over Europe - which shares an identical climate as the original Europe - while one slowly won and forced the other to retreat to Africa.
What I want
I want my Africa to be an even more hostile and barren continent without the rainy and fertile jungle. Even without a jungle, life the equator shouldn't be the worst place to live.
However, Africa should not become an uninhabitable continent, just one that makes life pretty miserable, which will be the main reason for some pretty desperate attempts to reconquer Europe for my losing faction.
I want my planet to have some distinct differences from earth while still being as similar as possible, while I don't care about changing the solar system.
What I need
- Europe keeps its climate
- The continents resemble shape and position of our current continents.
- Africa has no fertile ground aside from around the rivers
