What is to keep the pieces purchased in one theater from moving to the other.
Nothing. If the US chooses to build units in the Western US and send them to the Eastern US, then I see nothing wrong with this. I just feel there is already a lot built into this game that would make players keep most units built in the Western US in the Pacific, except for maybe the occasional plane. Firstly, having to send ships through the Panama Canal and having to send infantry two spaces (assuming there is still a central US) takes a lot of time. I understand that a player could just build planes in the Western US and send them east. However, in this game the US actually starts with a surface fleet that Japan can’t destroy half of in round one, meaning the US does not have to devote 100% of its resources in the first few rounds of the game to put up a fight in the Pacific, as it did in other games. Also, with Australia, China, India, and the DEI worth much more than they were in any other game, it seems as though even if Europe were taken, Japan would still be able to defeat all of the allies (minus Australia) singlehandedly if the US leaves the Pacific alone.
The purpose of having the split income is so that the US can’t just put 100 IPCs right into the Atlantic or right into the Pacific. If the US could spend all of its money on transports for the Atlantic, then I could see a D-Day happening 3-4 turns after the US enters the war, which is totally unrealistic. If the US decides to go 100% KGF and had to send transports around through the Panama canal, that could delay this by 2-3 turns. If they just built planes in the WUS, and assuming the US has to spend at least its 40 IPC WUS NO bonus in the WUS that would still be 4 fighters vs. 3 transports with 5 infantry and 1 artillery. While option 1 would certainly not be a bad choice, option 2 would help the US invade Europe much faster if built on the first turn after war is declared. If spending 100% of income in the
EUS, the US could just do an all transport and ground unit build turn 1 after DoW, fighters and tac bombers T2, and Strategic bombers T3, and then the US would have a much larger invasion force than if the income were split, since it would have more ground units from T1 build and would be able to get all of its planes to UK quicker from EUS than WUS, since T3 strategic bombers would likely reach UK a turn faster from EUS than WUS.
Likewise, if the US could place 100% of its IPCs in the Pacific, this would give a huge advantage to the US vs. having to place at least 40 in EUS because the US could build 2 extra BB in the Pacific T1 after DoW, making a nearly invincible US fleet right off the bat. Had the US had to put 4 planes in EUS rather than 2 BS in WUS, then Japan could hypothetically knock out much of the US Pacific fleet before the planes arive at the carriers that were likely built to put them on, giving Japan one extra turn of free roaming in the Pacific to take some valuable islands rather than worrying about 2 extra US BB. Oh, and they could also take some more islands with US airbases preventing the US from using those planes to scramble.
So while the US can certainly go all out KGF or KJF even with split income, the split would delay the US forces by one or more turns, enough time for Germany to gain some valuable ground in the USSR or for Japan to take a few more islands or stage an attack on Australia. This combined with the increased number of SZs making moving ships between theaters a lengthy task. This makes it more efficient to use units built in a theater in that theater.
