I think I saw a mod that gives a scoreboard on the side of the screen in SP that works sorta like Civ4's. (I think).
I never really thought much of it. When I played CivIV, there was a scoreboard on the side that I usually minimized because I played large games which cluttered up the screen. However, it was useful because when I went into diplo with other civilizations, I could see my relationship with the other civilizations right off the bat.
Not the case in CivV. While I'm able to minimize/open up the diplo overview, I have to scroll down the unorganized list of civilizations to find the one I want and then I'm unable to see how close I am to other civilizations when I'm in diplo talks. Not a problem for smaller games, problem for 18+ Civilization games I usually enjoy playing.
