Apologies if this should go somewher else or has been answered before.
I'd like to start a game with two competing factions on planet Earth, for a cold-war style alt-history RP game. I'd like to control both of them (which I believe is possible). I've tried creating a new game, but it only gives me the choice to create one race. I then turned on SpaceMaster mode and looked for a way to create an additional race, but couldn't find it.
Is what I'm looking for possible and if so, how do I do it? Thanks!
