Are you a trophy whore/completionist? Yes. Are you not? No. The pivots I would say are worth it if you enjoy free roaming, as they give you cheats to mess with. But otherwise, outside of crafting, the biggest incentive really are trophies and completion.

You don't really get anything but titles or trophies or whatever. Like I left every fort open, just so that I can re-infiltrate them in the future for fun. I find that more rewarding than having a side objective or whatever "completed" with no prize really.
