Yeah I guess there is that. I think it just would have been cool too if certain places stick to their historical timelines (I'm not sure if this happens in game if circumstance allows) to reverse history but actually be aware of it, which of course Id need pre existing knowledge about.
Although as you say, I can learn as I go. I'll wait and see if it comes up in the sale. I'm off from the 12th so don't have to rush
