Maybe there's something wrong with my CD, but in my last game of Civ as Rome, Russia was just to the north on a small island. They deposited some troops using boats, and a couple other guys approached from the north. They got next to my capital, and then declared war! Their invasion failed (barely), but I've never seen the AI invade like that before. Usually they'll just demand something, I say no, they declare war. Even when I'm on uneven footing, I'll manage to launch the first invasion, and soon it's a stalemate. But I've never seen the AI do that before!
