A&A original is far better than pacific and europe put together.as for diplomacy not enough players is a problem i run into quite a bit . that’s why it’s so cool when i get to play it.
In order to use World at war you will need the original or Pacific. I think the best game is a combination of Europe and Pacific on the World at War Map. Although I think Europe and Pacific did the oceans much better. Maybe I need to make my own map!
