Yeah, you beat me by a turn. The game was never in any real danger, needless to say. Sumeria and I had a fun set of skirmishes over some workers near Dijon (they changed hands six times I think) but other than that they didn't make much of a dent--pillaging a few tiles was the extent of the disaster. Giving them (and, via MPP, Persia) something else to do was pretty critical, I think.
As for the new game... yes, I was thinking first turn trades allowed, then DOWs. And I'd play it for space. I'm curious to see how the trade benefits (especially in the early and middle game) compare to the ability to continue to expand and eventually build up science farms.
Given this, can you live with something resembling a "standard" map? 70% water continents, standard size, middle settings on the weather conditions (though I can live with changes on this), and some middle setting for barbarians?
I can survive the Byzantines if you insist on that, but I'd likely prefer someone that would have a useful warmongering UU. The Ottomans came to mind as someone with a good (albeit late) UU, and useful traits for a builder as well.
