I'm in the midst of finishing up a game on the second run-through. I got stuck on a decent-sized continent with Ragnar and the other six civs sharing two bigger ones. The first time through I thought I was doing decently enough until he DoW'd and totally spanked me. Since I had slacked off on my military the first time, the second time through I made a serious effort to keep my power rating up and made really nice with him. I had him up at Friendly and kept him there (Open Borders, Brothers and Sisters of the faith, fair trade, helped us - the whole shootin' match). Not a single negative diplo aside from the usual borders penalty. The RNG actually behaved on the random events until late in the game when I got the jilted bride with Zara. Then a couple of turns later he just up and DoW'd me. As soon as he did, I checked to see if it might have been some other civ being an instigator, but I was the only civ he had contact with at that point. Does the AI just sit back and go, "Hmmm. It's 1300 AD and I haven't pillaged anyone yet. Think I'll go do something about that." Or is Ragnar just another psycho like Monty? The outcome of the second go-around was that I spanked and vassalized his hairy butt and left him with a couple or three cities out on some islands that it wasn't worth the hassle to take. If I can figure out how to get a foothold on their continent and take three or four good cities, I think I'll gift those to him and let him go after Zara and/or Augustus. But as it stands, I'll probably get a culture win before I can see whether that will work - bummer.
