Far from completed and done, an ongoign project, but there really is architectural and design competence behind it. You can download the demo from Steam. I did, and walked the ship an all 5 or 6 - mostly empty - decks, but the vision illustrated behind this really is stunning. This could become what I dreamed of to have when Star Trek Next Generation was a new show on TV. A complex starship wiht many floors and halls and rooms and cabins, all working, functional, and interacting technical systems behind it all.
