It's interesting to see how peaceful everyone's being. I guess it must be in part due to how huge the map is. In the previous (non-Dark Age) Vanigo game, on turn 30 I was fighting a war against all five other players, raising fields and taking towns. If I was playing as the Southerners in this game, I'd use the superior iron production to amass axe men and send them on the East: large food-empires are powerful foes in the mid-to-end game so you've got to attack early on and steal their cities if you've got weak growth.
Yeah, there are quite a few reasons.
1) The map is much larger. There is literally no need to be fighting over land before turn 100.
2) There are no critical resources. In the previous (non-Dark Age) game, both mana and iron was positioned so as to cause maximum conflict. Removing these removes a large part of the impetus for the war. It also removes the excuse that you are simply sending troops to protect your (already owned) resource point). Although there is still iron, there is much more of it, and every single player has some close enough that there is no way to snatch it from them without a full scale war.
3) The map is much larger (again) with rougher average terrain. This means that instead of units taking 5 turns to reach a enemy, they take 10 turns. Which doesn't sound super huge, but it does mean that instead of them being sure your troops are going to attack them (instead of simply sit on the boundary between your nations) 2 turns ahead, they are sure 5 turns ahead instead.
4) I was quite thorough in explaining my strategy this time around, which I suspect probably stopped one or two players from starting a early conflict.
