So I have some experience with turn based games and can muddle through with the civilopedia and wiki for strats, units, nations, etc. But the novel gui is killing me. Or rather, having buttons which I don't understand the function for is doing so. Can someone lend me a hand on those aspects of the gui which aren't the same in vanilla Civ4? What is going on with the icons directly above the unit information area (on the middle of bottom of screen). There's a bunch of dots looking like tetris, red and green plusses, etc. I have no clue what they are for, and I feel like know what your buttons do is the bare minimum to learn the game.
