It would be nice to see Germany re-worked into a science/engineering civ. Maybe they could do something like each great engineer improvement provides +4 science. The Germans are known for engineering. In America they have commercials for German automobiles. And they always talk about "German Engineering" as a selling point. If Americans hear that the something was engineered by Germans, then it must be good. But there is never any talk about "Chinese engineering", or "French Engineering", only German Engineering.
