Agree with this. The main problem when you share a continent is that you are often clustered into a tiny corner(i don't know why but you have less land ''per capita'' than pangea maps) and often with open land(i.e. few mountains and natural chokepoints). Then almost every AIs turn guarded when you settle more than 3 cities making every trades more or less tedious and not so much lucrative.
Right, and I wasn't going for a space victory. I was going for domination. And the problem was, until Navigation, unless I got lucky, I wasn't meeting 4-5 of the other civs, so as soon as I got into a war with my local civs, I had no one to trade with anymore.
But even if I was going for a science victory, with only 2 people to RA with, and virtually zero chance of us all remaining peaceful the whole game, it would be pretty damn hard. It seems to me the best bet is to cap everyone on your continent ASAP and then hope you haven't fallen too far behind...
The problem is, that's exactly what happens to me. The techs I have to go for to dominate my continent slow down my tech so much that I fall miserably behind and then have no one to RA with until Navigation, which is pretty out of the way from where I was teching for my war. If I chose a particular civ whose UUs were early in the tree, it'd be different. Maybe I should just try this with Montezuma or someone else with early UUs that can rush across rough terrain.
Actually, Polynesia might work too, because you could probably meet all the civs way early. And then just go tall. But whatever, basically it feels like continents is not well-balanced for Deity. I don't like beating my head against a wall to prove a point. ;-)
I think I'll just play on Pangaea for my first Deity Domination win. I was trying continents because I figured that I would get a huge advantage from early conquest and could then tech up really fast without outside interference, then conquest the rest of the world, but I don't know if that's realistic on Deity.
Edit: (Not realistic because out-teching the AI on the other continent without RAs and without focusing on science from the first moment doesn't seem to work that well, so by the time you leave your continent to conquest, you're behind in tech unless the capitals you get are treasure troves of wonders maybe)
