Yeah, I was just thinking recently that it's been awfully quiet on here the last month or so... Don't want anyone thinking nothing's happening.
That would be awesome if you could assist in further tweaking the town and settlement locations! I am no expert in Scandinavian geography, haha, most of my knowledge of the time period centers around the British Isles... But if you have the time and the desire (it's been an awesome recent hobby for me now), take some time to do some research on Viking Age Scandinavia, if not in a library, try to stay clear of Wikipedia, haha, unless it's to get an idea about something that you then can research and verify further elsewhere, haha
But there are many good websites and blogs and solid historical information on the time period and some of the major centers of trade of the area, many containing maps. Trick is to verify through some reading as to what was there, and when. Some will overlap the time period of the mod, some are from long after.
But it's been a very fun and educational research hobby, if you care to join in, that would be awesome! Please feel free to start reading up and maybe collecting some maps online and getting to know them a little. Then when you get a chance to see 5.2, compare what you see with what you know, I'm sure there will be lots of little improvements and adjustments that can be made to make it even better, since his attention is spread between so many different parts of the mod at the same time, and there is no "one map" of the area, due to not as much written records as say, England, had during that time period.
I will be doing the same as soon as I finish my little project, so as not to hold up the release of this awesome next installment!
