Star Trek Online, there’s really not much contest. Sure, Earth Spacedock is the “central” hub for most new players, but Deep Space 9 is the station that has seven seasons of a beloved series and is also one of the most memorable locations for players to visit. With the launch of the Victory is Life expansion on consoles – an expansions dealing with the Gamma Quadrant, which is intimately tied to Deep Space 9 – the designers took the opportunity to rebuild the station to look even better.
The work was aided by the fact that the Promenade (the central location of the station) actually had its set built on the studio, which meant the designers could use those floor plans and start recreating the exact sets seen in the episodes. Of course, the actual Promenade is a full circle and less than half of that was built as a set, but it was still a place to start. Check out the full article to see how the designers brought everything about the iconic station back up to more modern design standards.
