An interesting game which appears to be a digital version of the classic boardgame Russian Campaign Jedlo/Avalon Hill which I played to death back in the seventies.
Two big caveats however, no AI and a fifteen percent off price on Steam of $50.00. I bought it before it came to Steam and I like it, but I would be lying if I claimed that I would not like it a lot more with AI and a much cheaper price point. The UI also has a few kinks. Probably for nostalgic grognards only.
The game now has AI for both sides, and has been temporarily reduced in price to $50.00. I am a big fan of the old Jedko/Avalon Hill Russian Campaign and this is a decent digital version. Probably still for grognards of my vintage only.
Only get on steam. Buying direct gets you a license for one computer only, and they will not budge from that restriction, even if a computer goes belly up. The whole thing has a late eighties vibe to it, and most people, rightly, would not want to put up with these types of quirks from the past.
