Is it possible to remove an early building from the production tab and replace it with an upgraded version without loosing any buildings in other city's which already have that improvement.
Did that make any sense?
Wheathin had an idea about "City Improvement Packs" http://apolyton.net/forums/Forum11/HTML/000254.html
e.g.
Combine Granary and Temple
A city with either or both buildings cannot build the new building.
A new city without a Granary or Temple built, will only have the option to build the new building.
As wheathin stated if you obsolete an improvement all the buildings you have already completed will vanish like the barracks in Civ1.
