The Jackson Gamers have a very detailed guide to gaming the Russian Civil War.
The Perfect Captain has released a campaign system for his Red Actions! rules set. From the Captain:
We have completely outdone ourselves this time! What if I told you this was a campaign game that takes maybe 30 minutes to create from scratch, with limitless scenarios, a different map each and every time, and has counters representing the following armies and their equipment: Reds (All over Russia), Whites (Kolchak, Deniken, Wrangel, Yudenich, Komuch, Kappelites etc), Greens (Mahknovists), Estonians, Latvians, Finns, Lithuanians, Ukrainians, Poles, Armenians, Turks, French, Greeks, Japanese, American, British Empire (Including Canadians, Australians, and Indians), and Freikorps.
To go along with the previous post on Red Actions!, the free Russian Civil War rules, here is the Jackson Gamers’ RCW site. There’s plenty here to look at!
The Perfect Captain offers “Red Actions”, another in their series of superb free wargames rules. This particular set is designed for miniature wargames in the Russian Civil War. Like all of the Captain’s rules, these have superb graphics — but they are not just gratituous pictures. The thing that makes these rules so special is how tightly the graphics are integrated into the game system.
The Perfect Captain’s games are amazing combinations of form and function, with artwork that really matters to the game. They now have an expansion to their earlier Red Actions! Russian Civil War game that deals with the various nationalities that intervened in the strife. There’s also a new campaign.
