pacing

This is just what it says on the box - a simple mod that scales up tech and civic costs progressively throughout the game, so the tech pacing doesn't snowball way ahead of production to the point where units go obsolete before you've finished building them and the modern era starts in 1000 AD...

Higher difficulties means more productivity in a Civ world, stemming from both AI:s and players. We all know games tend to get shorter and shorter when difficulties go up, the games breeze through the eras. It always bothered me, am I the only one? What's your opinion?
