I just think it's awesome that we even have a map like this to discuss the fine points of MA map design and strategies.

To Semp's point about Green having bases close together, I think Red actually has the most dense base spacing. Look again and see if you don't agree. But Green does have the advantage of interior lines, while Red's overall shape is a bit like an 'S'. Blue also has interior lines but it is sort of 'hollow', with base density probably the least of all. Yet, it might be able to use its fleets as a 'mobile reserve' to bolster hot spots when the action gets heavy.
As far as adding additional Flak Bases, this was a discussion point in the map development thread here:
https://bbs.hitechcreations.com/smf/index.php/topic,404260.30.htmlWe've gone from zero Flak Bases per strat to two per strat, and then back down to one. I flew a heavy bomber sortie over Berlin (Green City strat) and was impressed with the reasonable amount of flak thrown up by one base, however I don't know if the accuracy and lethality are different offline than they are online. My buffs were rattled but not damaged by the offline settings.
I think the differences between the countries are interesting - Green is a classic land power, with difficulty projecting sea power. Its strength maybe its large land area and interior lines of communication (resupply). But it's fleets will basically be on their own if they make it out.
Blue is a sort of the opposite - its core is largely water, with bases ringed around the edge and spread sparsely in the central area. I really don't know how that will play out in the MA, a couple people suggest here Blue has the weakest and that might be true, but it also might be very difficult for other countries to get established footholds. It's strat targets are pretty safe in the rear.
I see Red as sort of in between - its got an unusual shape overall, with three different land areas containing supporting bases. Red fleets can operate in the North Sea and the Atlantic under an umbrella of protection from land bases, unlike Green or Blue. But it's strat targets seem to be the most concentrated and vulnerable.
Keep the comments coming, please. I'm no expert in terrain design or MA strategic play so this is a learning experience. Having a great time so far though.
EDIT: What do you guys see as obvious opening moves for the countries? Semp has mentioned Red should take Spain from Blue.
I see a large naval battle developing in the North Sea between Red and Green, I could also see Red making a drive on the Green port at Hamburg (P44) to bottle Green up in the Baltic.
I can also imagine a really costly sea battle in the Aegean as the Green fleet tries to break out of the Black Sea and the Blue fleet based at Taranto moves to intercept, with both fleets subjec to air attack from nearby land bases.
Really anxious to see how this map plays out a few times, and I hope it lasts very at least a couple of days when its up (if it makes it into the rotation, of course).
