While the gameplay is rather problematic in this one -lots of waiting with absolutely nothing happening- the worldbuilding of this title is what sets it apart for me; while the other games in the series have excellent stories on their own, replete with raw environmental immersion, final wraps most bits of plot up with a neat bow, and fleshes out the world in a way that makes me want to see some kind of manga/show because of the universes excellent storytelling opportunities, and grimdark nature. Also having like 100 playable ships, complete with lore tidbits is neat.
