I've been really excited for a long time now about the new map, but I know this is still going to take a long time (since Leoreth plans this for v1.17). And since I've been bored recently playing DoC with other civs not in the right pace of tech, I started making the 600 AD and 1700 AD scenarios in my free time. There has been lots of progress for both, although surely there are still lacking stuff (esp. buildings) plus a lot of inconsistencies since I only bothered to edit the terrain and resources along the way without modifying the base 3000 BC one. I know the map still needs a lot of polishing, and this may be a bad move, but I think it's okay to do the scenario files again just in case.
I didn't simply copy the two scenarios, though. What I made is a much more populated version, with more cities. Also, in the 600 AD scenario, I placed Persia (Sassanids), India (Gupta), Ethiopia, and Maya. Persia and Maya should collapse easily within a few turns, though, and as it is intended to be such, they are marked unplayable in the scenario. In the 1700 AD scenario, I put an alive Moors and Italy (the latter should have a decentralized civic though).
I've started a 600 AD game with the new map (currently on the RC tag of the develop branch), and edited Python stuff along the way. I'll work on it some more before pushing it to a branch on my fork.
In the meantime, here are screenshots (1099 AD, Marathon):
A lot still needs to be done, though. Areas.py still lacks a lot of edits (although I've edited flipzones for most civs already, the exceptions are a hassle though esp. for irregularly shaped flipzones). I've also started editing RiseAndFall.py with updated plot coords for hard-coded ones. I've been for a long time wanting to edit the settler and warmaps, but I have little clue on how to do it--I had to turn off stability to play this without weird stuff happening like southern Persia flipping to Tibet. We'll see where this is going, but so far I'm enjoying what I see.
