The guides are great, but should never replace in-game information. Guides should go beyond what can easily be displayed in-game and provide insights or ideas. They shouldn’t just be lists of things that the game developer didn’t include in the UI.
I would love a more “beuracratic” method of maintaining my kingdom. Perhaps a nice fact sheet showing tribute levels, bonuses, times tributed, and so on. Include the ability to upgrade kingdoms from that screen and I have a kingdom interface that really makes me feel in countrol of the realm. Clicking on the name of a kingdom to jump to its detail page would be an excellent feature as well.
I like this idea, but until it happens the guides cover the gap well enough I suppose.
