What are the names of the individual regions? I get that the blue area is Wei, but what is the central bit called, for example?
Here's my thoughts on gameplay:
Blue area (Wei) (+9)
Liang - 3 terrs, borders: 1 def /1 attack. +1 bonus
Bei Ping - 2 terrs, 2 def / 3 att. +1 bonus.
Big Blue - 9 terrs, 6 def /7 att. +5 bonus.
Red area (Wu) (+12)
South Red - 5 terrs, 2 def / 4 att. +2 bonus
West Red - 5 terrs, 5 def / 5 att. +5 bonus
East Red - 6 terrs, 3 def / 4 att. +3 bonus
Green area (Shu) (+8)
North Green - 7 terrs, 4 def / 3 att. +4 bonus
South Green - 4 terrs, 2 def / 4 att. +2 bonus
Blue area (Wei)Unless you have a good drop here, none of these areas are particulalry attractive to go for.
The only way I can see Big Blue being held, is by someone having a good drop there and on Liang.
If you don't have the two +1 areas, I would suggest that you're not going to capture Big Blue until late in the game and you're on your way to a win in any case - it's a bit like Asia on classic, with two mini Austrailia's.
Personally, I would be inclined to up Bei Ping to +2 to make it a bit more attractive, and match other regions. I'd consider increasing Big Blue to +6 or +7.
Red area (Wu)The red area attracts the highest overall bonus, and the +2/+3 regions look attractive prospects. to start at. In the East, you can hold the whole area with 2 terrs, as nobody is likely to be worried about losing Xu Chang early on; but you've got a lot of armies to battle through unless you have a favourable drop.
The Red Left area in the centre of the map is going to be difficult to hold. It sort of equates to Europe on Classic - but the bonus on its own is not enough to fort and attack.
It might be worth shortening the mountain range by Wuling, so that Han Zhong (green) and Jei Ting(blue) also border - this way the red area has to worry less about being the stop-gap between blue and green??
South Red has a half-bottleneck, which makes it an attractive option if you get dropped near there, but less so if you don't.
Green area (Wei)If you're trying for a 'big' bonus, then North green is going to be your best bet, as it has the fewest 'attacking neighbours'.
South green is also attractive with the half-bottleneck, although at the start, the number of attacking neighbours would make this a bit harder to get if you're trying to beat the drop!
I might be inclined to make both areas +3.
General ThoughtsMy general impression is that the Big Blue and West Red areas will be left alone until the later stages of the game, and that the best area to get dropped would be Green, as it has the best chance of expansion and getting the whole kingdom.
It reminds me a bit of the Iberia map, although I'm not sure the small bonusses are that easy to get; and expansion opportunities are fairly limited.
