I enjoy so much about Blackice. However, I stopped playing because
the focus tree stinks. Focus tree forces you to follow historical road such as requiring that you cannot do non-aggression pact between Germany and Soviet Union until August 1, 1939. I love the economic system in Blackice (other than the fact that it makes tungsten worthless). The units templates, and equipment are much better in Blackice, and technology tree is vastly better. All this stuff though is a matter of preference.
My suggestion is to break down Blackice into five separate mods that would be compatible but would allow you to pick and choose which to use.
