So, I started a new game of Stellaris with a few light mods. I have some time on my hands, about 14 days. Despite playing Stellaris for over 600 hours, I've never finished a full game. With that said, I'd also like to dive into EUIV at some point. I did play EUIV briefly in the past, but I never truly grasped the game's deeper mechanics. Fourteen days seems like it could provide a foundational understanding of EUIV. Who knows, EUIV might become my new favorite game, especially considering the vast amount of content available for it. On the other hand, Stellaris feels like comfort food; I can relax while building up my space nation. In my quest for an answer, I'm once again turning to the brilliant minds on Hexbear to assist me.
Kind of, it's probably as complex as Vanilla Eu4, IF you include all the DLCs.
You can also just a lot of things to be automatic, so a lot of the complexity is optional.
