DLCs - Must-Haves and Nice-to-Haves

[Cybvep]

Hi folks. There is a nice EUIV sale on Steam and I am considering buying EUIV along with some of the DLCs. The standard price of DLCs is high when compared with the base game and even on sale it would cost a lot to buy ALL of the DLCs. That's why I would like to know which DLCs can be considered as must-haves and which are simply nice to have. Obviously I am not asking about unit and music packs here, but "expansions" like Mandate of Heaven, Art of War, Mare Nostrum etc.

Art of War and Common Sense are the only "must-haves", in my opinion; when you read tutorials and stuff a lot of people will assume you already have them. Cossacks and Rights of Man have some major features and it's probably worth getting them too but you don't need them in the same way you do for the first two (not that you need the first two, really). Past that most of them have a more regional focus, so you can probably figure out based on that if you want them, although both Mandate of Heaven and Wealth of Nations have some significant global features.
