Tough to fit all the options into a poll like this.

Although the Danes are without a doubt an essential faction, there was much more going on in the Baltic and surrounding country during this period than that.

The Svear and Götar would be perfect to include at game start, the Fairhair dynasty in Norway, the Finns, Tavastians, Karelians & Sami in Finland. And that's just around 1100, lots more moving forward in time to explore.

It would be great fun to see a Baltic/Scandinavian mod.
