It has probably been said before, but I would love mega events like in the Dread Lord series. Of course like pirates, it could be toggled off.
I think its real place is in SP mode. When I play the computer, I want a better AI, but I don't like the idea that it gets buffed if I choose a harder AI, therefore I play random AI's. Mega events are game changers for all. Usually I am beating the computer pretty bad (against real people I get my ass handed to me), and this would allow for me to say WFT???
I have asked for this since the 1st Sins. I love the beta Rebellion though, just thought I'd chime in.
