My apologies for not putting up a video on the weekend for the trade course. I did not want to rush into it, feeling that more thought and organization was needed. Plus, I suppose, I felt strongly inclined to work on my world rather than describe it.
I do have something to show today - additional seagoing trade routes that I've worked out. Excellent versions can be found on the wiki, but I'll put up the images here so blogger can make them fuzzy.
I finished the seas around Arabia and India a week ago - easy stuff, really - so I'll put those up first:
The reader will have to open these in another window even to get a sense for them; they're just too darn big. Like before, lines are based on shortest distance routes between trade ports that are able to import from markets up to 10x their own trade number. The trade numbers shown on the map - ignore the red/yellow coloring, it means nothing. As I did trade ports, I generally changed their color just so I'd know they were done. This isn't consistent and nothing should be read into it.
Here's the one that took me all week (finished it yesterday. Wasn't quite as bad as the Mediterranean, but Northern Europe was complex nonetheless:
The series of straight lines across the North Sea shows the relationship between specific Belgian and French ports and their Norwegian counterparts - no doubt this is not coincidence. I suspect the placement of these port cities reflects the relationship between shipbuilders and their supplies of timber and pitch.
Obviously, this map will get a lot more complicated whenever I get around to adding England/Scotland to the system. That's another day, however.
