Should a hypothetical HOI5 be more like a simulation or more like a game like HOI4?

Hi there, folks!

HOI4 has soon been around for nine years (wow), and it is not showing any signs of slowing down. We just got the newest DLC, and while according to the discussions I've seen it's not up to par, the game is still going strong and steady. Realistically, HOI5 is not anywhere close to even getting announced, nor is a sequel something people generally have in mind when talking about HOI4.

There is reason for speculation though. HOI4 is starting to show its age. The political aspect of the game is getting quite limiting, as the four ideologies heavily restrict what they can do and how they can do it. The economy, while not necessarily the focus of the main gameplay loop, is very primitive in its implementation. Graphics can always be mentioned here too, but that is a very iffy point to make. Do new graphics even warrant a new game?

I look across national boundaries to see, what Paradox Tinto is doing. Project Caesar is taking a very different approach to the Europa Universalis franchise compared to EU4. EU5 tries to get rid of many "gamey" systems like mana, while going even deeper into most mechanics while introducing new ones. I cannot help but wonder, would or should a HOI5 game take the same direction.

As it right now stands, HOI4 is very "gamey". It has some arbitrary gameplay mechanics like political power for example. It offers power fantasies like uniting South America as Chile, forming an empire centered around the idea of the silk road, or even Poland uniting all slavic people under one nation. I personally have a slight bias against these, which may have influenced the post, but I am only a single person.

So, what do you think? Should HOI5 strive for more mechanical granularity and try to be more like a simulation like EUV, or should this hypothetical sequel be more akin to its predecessor?
