The name of the communism game in general is, at first, trying to capitalism the shit out of your country. Break up the power of the landowners, educate the populace, secure resources "by any means", industrialize and develop, and so on. Interventionism is generally a good policy for economic development. If done right, you get to the point where you have a modern, industrialized nation with an angry proletariat. Unlike real life where those states placated them with social democratic and progressive reforms, be as stubborn as possible in a way that empowers radicals. Then the magic happens.

If you don't care about aiming for achievements straight up, you can use console commands as training wheels (though don't actually use them until you need it so you can learn).
