Glad you like this.Thanks. I don't know if I will make a map myself, but I love this alternate geography map.
I'd say that's possible. Given it's an island, it would make sense for it to be a naval power of some sort.More generally: Do you think an independent Doggerland has potential to be a colonising power in the Age of Exploration and Colonisation?
Plus, if we're honest, it's surrounded by Scandinavia, Britain and the Netherlands... All of whom had pretty strong naval traditions and established colonies (though Denmark and Sweden's were a bit more modest compared to the others in the Age of Exploration). Assuming Doggerland has a somewhat similar cultural make-up as any of those, I don't see what's stopping them. Not to mention they'd likely have to deal with these neighbors.
Of course, there is also the simple answer: it's AH, everything is possible even if you have to use ASB.
