During a game in Civilization IV, you can see a score for each civilization (on the bottom right, above the mini world map). Is it important to be the top scoring civilization at all times? Or how much can your difference with the top scoring civilization be before you're unlikely to catch up or win the game?
I have started quite some games already, but played only a few of them through completely and those were at lower difficulty levels, as fully completing a game can take quite some time and I'm still learning; so I don't have a feel yet for how well the score reveals whether you're on the road to victory or not. So far I still tend to lose my top position at some point, typically when I get into a war. I can keep my own score during the war, but some other civilization quietly starts to overtake me. I'm not sure how much I should be worried about that.
Do expert players make decisions based on their score? Like getting out of a war before you fall behind too much score-wise?
