How do you have fun in Hoi4? Feels like the game is rng.
Not sure about RNG in HoI4, but the fun to me is in guiding your chosen nation to glory and success, and powering through the challenges you might end up facing while on your path to global domination. Or the fun could be in setting a challenge for yourself, and seeing it through. Stellaris is especially good for that since you can customize nearly everything about the interstellar empire you're playing as, and everything is randomized so you never have the same game twice.
