All Paradox Interactive games ever created 😂
The worst I had was Hearts Of Iron IV. I played a 2h tutorial only to not understand a single thing the real game threw at me afterwards...
Also, the tutorial has suffered bitrot quite a lot. The game has seen many significant changes since release, but the tuturial was only partially updated to reflect them.
I come back after a major patch or every 6 months and its all changed again! Which is good as it keeps it fresh, but the tutorial is very lacking on the changes.
It's not nearly as complex as it initially looks imo, but I also play with a million mods some of which make the game needlessly complicated so maybe the vanilla game just looks simple in comparison to me now lol
You gotta just start with an easy country. The CK2 community used to call Ireland "Tutorial Island" since it was low key and a good place to learn the mechanics, same with Spain in EU, or Belgium in Vicky.
About what Hearts of Iron? I tried that game once (3 or 4, don't remember) and basically gave up when the tutorial ended and I still had no idea how to do anything.
I still don't know how to play hearts of iron IV. I'd love to learn but I'm a trial by fire learner. It's really hard for me to make it through a 2hr YouTube tutorial with monotonous robot voices.
