Fallout 3 dlc was better than the entirety of starfield. And you proved my point nothing you did really mattered in Skyrim which came out in 2011 (same with oblivion in 2006), and now again in starfield. Bethesda hasn't gotten over the hump of making interesting role playing mechanics in their games. Also the dark brotherhood questline in oblivion was better than any faction in this game, and multiple like the thieves guild in Skyrim are better. The ryujiin quest line felt like a cheap thieves guild equivalent.
There's no options in the ryujiin questline other than to actually correctly identify the culprit or frame someone else, which in turns leads to absolutely nothing different by the end, and the conclusion is the same. You can do the last couple missions guns a blazing, and nothing changes. It's the same conclusion. And that's just one example, basically nothing in the game matters. The game is a mile wide, but an inch deep.
The uv and crimson fleet quest lines were cool, but at the end of the day it doesn't really matter what you choose at the end.
No, that example you gave doesn't matter. You have to choose between the uc sysdef or crimson fleet by the end of the quest line anyways. In my game uc hate me because I choose crimson fleet over them. But you can still visit uc controlled planets and everything, they scan your ship when you enter one of their systems, and then yet you land anyways even if you slaughtered uc members before.
