Star Wars notwithstanding, I think it's time for a real space pack. Something loosely based on Star Trek, but not Star Trek, a Sims version of Star Trek. And not a ship. My idea is to have a space world set in a space station. Think Deep Space 9. Using DS9 as an example, a ring consisting of three levels around a main hub that is the three story "park" where everyone can go to relax and view the stars. The ringed levels could be divided into a residential ring, a commercial ring and a control/engine ring. Around the outside of the rings are the "lots". Varying sizes of open rooms much like how apartments work with the outside walls being fixed but interior walls are editable. Elevator turbo lifts get your sim from level to level and each level would be a separate "neighborhood". Your sim could take a shuttle into space for adventures similar to the rocket and Batuu quests.
There could be jobs as part of the stations crew: captain, medical personnel, security, etc. all of which we already have but tweaked for a space station. And jobs in retail, dining and other odd jobs around the station. The station townies would live on the station but, as in other worlds, we never know or see where. With the Star Wars costumes, we can populate the station with many different alien types.
These are a few of my ideas. What are your ideas?
