As to the damage when/iff they finally capture the oilfields, a troop of Boy Scouts with a hammer and a box of matches could severley damage an oil refinery, let alone trained engineers with access to explosives.
And yet, the engine allows us to capture those bases undamaged most of the time. Game is borked, I tell you. And the OOB doesn't even includes boy scout units (with Lt Akela, their commanding officer).
Seriously, the game gives Palembang a disproportionate importance, because oil/fuel is modelled separately in the game, and because the sources of production are all concentrated over a small number of hexes.
This has consequences for both players : it creates Palembang fortresses options for the Allies, and means Japan should rush to take Palembang (the most important hex on the map), and plan his fuel usage throughout the war in advance. As such, taking Palembang badly damaged is viewed by many JFB as a shattering event. Somehow, it seems worse than the loss of the KB (but this is historical, eh?).
I'm trying to find out/predict what is going to happen with the Japanese economy so I can continue to fight back. I still need a lot of tanks, planes and ships to get my revenge!
Also it is not scenario 2, but DDB-C scenario 1.
Tanks and planes are fine, they aren't very costly (a fighter is a mere 36 HI), and don't use fuel. Ships are the main issue, because building them costs a lot (even more if you accelerate them) and sailing them uses fuel. So, it all boild down to questions like :
- which ships do you really need? (build what? in scenario 1, you don't need most of the merchies, in DBB-C, it might be different)
- when do you need them? (ie accelerate or not)
- when you have them, will you have fuel for them? (because if you don't...)
Another point you might want to check is your current fuel usage. It is very easy to use a lot by having task forces sitting undisbanded in port, or running small errands with your big fuel users, KB and the BB.
My 2 fuel points...
