That's a very good question. I don't even know if there's a Mongol invasion in a Random start. It's possible there isn't, as I don't think most historical events would be adapted to the different starting positions for the cultures/individuals they affect.I have everything gameplay related (not all the purely decorative ones, though).
I also vote no sunset invasion.
EDIT: actually if we’re randomising then there’s no particular reason not to include SI is there?
