oh boy, now that would be hell of a game.
imagine victoria 2, except it has to include realistic simulation of democratic elections (so already you get something of a game within a game; such a broad subject if it were to be reflected in detail, and it should be given it's of immense importance in a game with a concept like this, would require hundreds of separate mechanics, and don't forget the major nations today have very different way of running their elections and very different political systems even though they share the same ideology, so that would be a doozy), the complex nature of modern macroeconomics (basically providing player with a way to conduct both monetary and fiscal policies; highly developed representation of global market and ways to interact with it, influence it and adopt your economical strategy accordingly to it's current state), trade, and trade would have to be tied to both technology and labor division, and technology on it's own currently would be a subject itself bigger than anything ever reflected in any Paradox game before, then you have military which also has to be conducted with high relevance to technology, and while there are many more aspects of running a nation in modern world, those i have listed so far are all closely intertwined, they impact each other to a huge extent. collective attitude of society would determine the extent of your success and that could also depend on a multitude of things.
imagine the research tree too, given the fact that there is not a single aspect of national progress that is not being impacted in a very major way by scientific progress.
oh, right, and there is also space

basically victoria 2 concept + parts of hoi4 concept in much greater detail and complexity + some parts of stellaris concept closely tied to a reliable simulator of internal and global politics. education is already a factor in vic 2 but it would have to also become much more complicated since it's basically directly proportional to the extent of your success in economy, trade, technology and subsequently everything else there is. and we have social issues today which would make social issues of vic2 look like a bit of silly, simple fun.
so basically, love the idea, would definitely buy it and play it, but i pity Paradox if they ever go through with this
