I was thinking that it would be a really good idea if there were more biomes for space. So, for example, you could have:
- Polar Orbit Space, (near and far)
- Extreme High Space
- 45-degree Orbit Space, (near and far)
- Equatorial Orbit Space, (near and far)
And others like that. To of course balance it, you would have to lower the science gain from science equipment in space. But it would add more reason to have orbits with different inclinations.
