I personally think that a hearts of iron darkest hour with Germany would be spectacular idea. I do not believe there currently is one in existance. You did mention that hearts of iron is one of your favorote games, Stalin, and do hope you will use this request.
He did Kaiserreich. And he did Hearts of iron 2 on his old channel. http://www.youtube.com/playlist?list=PL520FF8FC9454FC06&feature=plcp
I never noticed it. Is the old channel you are talking about josefvstalins channel or someone else's channel?
