I’m not too keen on changing the troop values for the various countries. I think having their ipcs go to the controlling nation is enough.
You bring up a good point about the allies attacking neutrals, but these rules are really about bringing more options to both sides rather than taking them away. I have no problem making Historical Sacrifices provided it results in improved game play and fun. I’m just looking for simple, perhaps a short paragraph, to give the rules for various Neutrals.
Back to Sweden. I maintain the greatest fear the Swede’s had was Communism. When Stalin attacked Finland they sent support to them. They allowed transit rights to the Germans so they could fight the Russians. I am sure they were entertaining thoughts about joining the allies in order to keep the Russians out of invading Scandinavia. Even if these things are not true, I am leaning towards rules that follow the ‘evil communism’ spirit.
Perhaps giving Germany the option to activate Sweden when the time comes is best? Germany can then look at the on board situation and decide if Sweden being activated is wise, or if it is just giving that territory to Russia. I am thinking this would not be a round after round decision though, Germany gets 1 shot at Sweden.
