The colored major and minors are people’s own creations. And I find either 2, 4, or 6 players is best (6 is a stretch b/c of you could get knocked out). And, for example, if i play a 4 player game i divide the powers
Germany and Italy
Japan
US and Russia
UK, Anzac, France, China
6 players
Germany
Japan
Italy
US China
Uk France
Russia Anzac
If you’re new i would either recommend the allies for a two player, probable UkAnzacFranceChina for 4 player and either italy, USchina, or UKFrance for a 6 player. Whatever you do, don’t play as Japan (and probable not Germany either). I’ve played my fair share of new players and Japan is disastrous. At least with Germany they know to go in the general direction of moscow. But with Japan i’ve seen people ignore the DEI. Game over.
