we need cold wra and PLANES MAKE PLANES JUST DO IT LIKE ITS EVEN ON THE ROADMAP

Bolshevik revolution'd be simple compared to what mods have already done, at least relatively. Shift some Russian units to the Red Faction and have fun. Of course you can further that by changing hte decals of some to better reflect post-WWI Red and White Units, but that's already been done and more by other modders.

Things'd get a bit spicier as we go further. Dealing with planes and vehicles like the Tachanka (imaigne a mobile "vehicle" with a maxim gun firing). But it'd probably be doable.

Annnnd it looks like someone has put the Bolshevik Revolution in.

Good news.

WWII seems to have a healthy modding community with some mods in too.
