After the hotfix update, with the help of free oil, I could achieve strategic victory playing as Russia.I have manage to get partial victory playing as Russia. Key is to encircle the large enemy groups in first strike and destroy them before you ran out of resourses. Kind of Blitzkrieg. I manage to do that on front towards Ukraine and later send all those forces to the other parts of front which make situation easier, but, still hard. At the end of game the front was on the borders of Poland and East Prussia.
Scenario in general need a lot of improvements, example: Strategic redeployment option is off, why? And problem with Russia having constant lack of oil looks like a bad joke.
There is also one bug, when Finland enters the war one Russian army on their border still remains locked.
(Though the division in berlin will be eliminated by german army soon)
