Recently I was making planets again and I was wondering if it was possible to have a world consist of mostly jungle and rain forest biomes. Also with that I was wondering what would need to be the land to water content of the planet to be mostly or hopefully all jungle like this. Is there a way I could have large land masses with less ocean? I also was wondering what the atmosphere would be like. Would it be constantly raining or more normal like here on earth?
The whole point of this world is to have a planet covered with jungle that creates a hostile environment for invading races to the point where futuristic military hardware is trumped.
