I’m new here, but maybe this is a partial answer…
I’ve glanced at all these house rules, but didn’t see it here. Some postes indicate that part of the wbsite was lost.
I’ve got a friend(bet you’ve heard that one before!)who told me about oil deposits in Borneo/Celebes. He likers to play with a 3 IPC value on Bor/Cel. I think he reduces the FICB and KWA territories IPC value by 1 each(not sure as I only played this variation once and don’t usually play with this guy.)
About three times I have played a variation that added 1 IPC to the Caroline Islands, Wake, and all the southern Japan holdings(4 of them.) Japan territory lost 3 IPCS, FICB and KWA lost 1 IPCs each.
EUSA lost 1 IPC and WUSA lost 2 IPCs. Midway gained 1 IPC and Haw gained 2 IPCs. China gained 1 IPC taken from Sinkiang(-1 IPC.)
This variation seemed to tempt some to do a lot more in the Pacific. IMHO, if Japan does USSR survives and Germany falls…if US does Axis has a better chance.
If I ever play with this gang again it will be with reduced or no alterations.
Try your own!
