I am a big WW2 and WWI fan and a fan of alternate history so this game looks interesting especially now that it has matured for a while and has some options. I do have some questions, I am interested in starting out and having all 3(?) factions at once.
Is all that I need the base set and the one that adds the Russians, or whatever they are called ? Also do I buy the rulebook separately or as part of the base set box ?
