I believe you are correct. The “bonus” 30 the US gets when it’s attacked early is to compensate for not having extra money while “at war during collect income”, for example:
The US is attacked turn 2, gets 30 IPCs immediately so they have that to spend when it becomes their turn. If this were NOT the case, then the US would only have their initial 30 IPCs to spend during “war time” which wouldn’t make sense.
I’m kind glad they released Pac at X-mas (test run). Hopefully our feedback and more internal testing will make for a better global game when you combine them. Keep in mind many of the political rules have went through a transformation that will aid in the upcoming game. If they released it as one game this summer, many of the problems that have come up over the last few months would still need to be fixed.
If US decides to build up in HAW seazone, your aircraft are useless for a complete round (or more). Because you can’t fight that seazone (6 spaces). As US player I would just sit tight, build up and move to Japan via a northern route. Or go to Indies via southern route (Australia). Or build up TR with loads of cargo to take out Carolines. For every fighter it costs Japan it costs an inf for US.
And I think it will be a very dull way to play, or am I mistaken?
