@Carolina:
In general I agree with your list of standing neutral forces. As to how neutrals react towards aggression, should be a matter of influence. To represent diplomacy and influence, there should be a mechanism for spending IPCs to influence a country’s alignment (pro-Axis or pro-Allied), but there should be an element of risk when attacking. So, without any play-testing, and as a starting suggestion I would propose something like comparing the [Side 1 IPC influence + 2d6] minus [Side 2 IPC influence + 2d6] (the 2d6 rolls are the element of risk). If the result is >= then they are friendly. The alignment determination would be after the combat move and a friendly result would have the neutral welcome the invaders with no battle, otherwise combat! Once aligned in this manner - their alignment would never change.
Sure if you want to add that, but I want to keep a general house rule which will appeal to most players.
@WILD:
I think the true neutrals ban is pretty ridiculous, and like the list you have put together for individual standing armies that includes some better units and a bit of navy (might be a bit over zealous though)
I have mixed feeling about countries that had colonies linked to them. My first thought was that if a country like Portugal was invaded that their 3 colonies would be immediately activated (pro axis/allies) against the power that attacked the home country. Then I thought if Portugal was attacked would their colonies actually pick up arms, but for game purposes yea I think you do it. However if Angola was invaded would Portugal go to war against the aggressor?
Do you lump the Iberian peninsula together and their colonies? Portugal feared Spain joining the axis and/or an axis assault through Spain. They also had an Anglo-Portuguese Alliance for over 600 years that Portuguese Government announced was still in tact at the start of the war (The Brits decided to let them stay neutral). So if Spain joined the axis, or Hitler invaded Spain, yea Portugal would join the allies (go pro allies). However if the UK/USA invaded Spain, Portugal certainly wouldn’t join the axis.
I am testing a game right now where I have messed around with the neutrals. I have tweaked the inf and gave some better units (art, tank, ftr) and some navy to the neutrals that matter like Turkey, Spain, Portugal, Sweden, and Argentina. I have even split Turkey (east and west) and Spain (north and south) into 2 territories. What I put down is very similar to what you listed (a bit lighter). The rest of the neutrals like in South America and Africa I added one inf to all. If they had 0, they get 1 inf; If they had 2 they now have 3 etc….for simplicity.
Was also looking at a broad rule based on IPC value.
0 IPC value get 1 inf unless listed otherwise on the map (most won’t get invaded because they have no value).
1 IPC value they get the inf listed + 1 art
2 IPC or more they would get the inf listed +1 art, 1 tank
Place a dd in countries like Port, Spain, Turkey, Sweden, Argentina
But that doesn’t seem work in some cases?
The problem with your setup is that things like the U.S. invading Spain and the Axis invading Turkey just becomes a no brainer at that point and possibly game breaking. I have modified South America a bit so they aren’t so ahistorically strong.
