Finished this now.

Went with the "Hero going against the board" storyline, basically listening to this Welles guy all along. All in all, the game felt really really short. I don't know if I missed out on a lot of side-quests or exploring but didn't feel like it.
The whole game was weird. It was nowhere near the size of any of the Fallout games for instance, felt like. I also kind of felt it was ruined a bit by the environment on Monarch, which felt like the largest portion of the game. Just the colours were completely off on that planet, it sort of felt like everything was inverted or something and it just made me want to get out of there.
Byzantium felt very underwhelming as well. The design of it felt a little lazy and it just didn't feel like a bustling city.
All in all the game was kind of fun, but by the time I was done with it I felt like I should only have been scratching the surface. And the Colony never really felt like a very big place. I envisaged a little more epic space travel and diverse settings etc.
Falbrook was the best place of all.
