Since the principal antagonists appear to by defined by nationalistic, religious and possibly racial fanaticism I assume (by process of elimination) the protagonist or at least factions you can ally with will be defined by more worldly concerns. I can definitely see those worldly concerns manifesting as both self preservation and justice along side baser material interests. And, judging by Ubi’s track record in past FarCry games, those interests will be mixed up in a big, morally grey slurry; releasing prisoners in one mission and smuggling drugs in the next all with the same people.
I also suspect that Ubi will take the political and social events of the last few years in the states to populate this landscape. I can deffo see them dropping in a DAPL analogue, a pastiche of BLM, border patrol militias, bootleggers and beer smugglers, meth labs and cartels, etc.
I’m sure they’ll revel in Montana’s history of Bad Violence (you know what I mean by Bad Violence, right?), but based on what (granted, precious little) we know, I can’t imagine them turing on Greed in any capacity beyond just more of the same edgy Both Sides Do It crap you get from any other AAA game.
