Nobody anticipating any kind of atmospheric planet, apart from gas giants? The "glide mode" for planetary landings is early prep for this. But planets don't make money in the store ...... unless it's base building.
New Era 2 (I'm getting ahead) might introduce Elite:Terraformables ..... you get the chance to terraform planets and introduce "life" and see how it develops. That would be a combination of ED and Jurassic Park, though.
I like the New Era 2 but get ready for mass-extinction griefers!
