I'd actually love to see less trepidation about giving players spaceships at level 1. Hell, I'd love to run a game where each player has their own spaceship from the get go. Maybe they could play a band of plucky rebel pilots trying to stop a massive evil empire :)
I want to see classes such as the thunder scout from the Thunderscape books. I want the freedom to be able to have my own space bike (maybe similar to a hover bike or sparrow from destiny) and treat it similar to my animal companion. After all that is what that entire class is based around.
