Hi all I'm testing for first time Strategic Commander WWII GC. And I have a basic questions to veterans gamers of this game. - How is possible that Japan has more MPPs than Germany in beginings of 1939 campaing? And, How can we increase the available MPP of any nation? - In diplomacy, you can spend some MPP over any country to gain something. What does we will win with it? For example, if we are Germany, do we need to press Italy? - Can we modify the units under command of any HQ? adding or removing units? For example, can we add some unit to Bock HQ in 39? -- I will add more basic questions -- -- If there are any manual of game, let me know please! -- Thanks
