Another criticism I have is the amount of Linearity for gigs, Phantom Liberty makes it very apparent how less branching paths and choices this game has for most of the Base Game's run. I sometimes feel like some gigs could offer diplomacy, but all I get is the option to kill.
I dislike the Sinnerman quest a lot. First of all, there is no alternative choice/path you can take the questline for like 90% of the quest, its all basically linear. The options are either "guess I will play along" (continues the quest) or "nah, I am out" (ends the quest).
