This looks like this may be the spiritual successor to Silent Storm. I loved that game. I have every version of it. I would love another adventure like the one in Silent Storm... Count me in!
I don't think this game has anything in common with Silent Storm aside from alternate history setting. It's even alternate WWI, not WWII. It's much more closer to Company of Heroes, it's an Real-Time Strategy, while Silent Storm is Turn-Based Tactics with RPG elements.
But about the setting - it's certainly captivating and made with love and attention to detail. If you liked Silent Storm for it's setting, you might very well enjoy this one. Just FYI.
