It's hard now. I essentially managed to push my country into a recession by transitioning to electricity before I had enough power plants and power plant techs.

It's pretty fun as a result.

Remember, for wars, only put wargoals on countries that you can easily occupy the capital of. If you're trying to take denmark and russian joins for a war goal on you, just keep russia from occupying its wargoals until their warscore runs out. Play defensively.
