I love seeing people do stuff like your Kyoto Osaka IZ: it's just really fun to set up stuff like that and Work in canals.
The new rules really make japan a blast. Unique factory, all the green districts give IZs +3, easy to build more districts for +1's...
I definitely feel that Germany is a whole level above even them, but it's more stressful because you need to plan a lot better. After seeing your picture I rolled a Japan - small continents.
I love that they integrated the new map pin system. It makes the IZ planning infinitely better.
Tack Life:
I think i might like the look of a field of pins more than I like the actual districts!
