Mark, its a house rule, its not supposed to play out exactly the same way in your basement as in mine. In my basement it would be as free as possible, while in the residence of Baron Munchausen it looks like its gonna be some restrictions and limits. In most games you only see 2 or 3 players, so I doubt it will be a lot of arguing about the sharing. If you play in a club and 8 people sit around the table, I bet they stick to the OOB rules.
Anyway, if Germany get all IPC in one game, then I figure Italy or Japan get pretty weak. But the beauty of the hidden nature of this rule, is the Allies don’t know for sure where the money goes. Both the Allies and the Axis have to guess what the other guy do with his starting cash
