CivAssist II is a program designed to remove a lot of the tedious micromanagement from Civilization III. In addition to this, it also provides a lot of extra information to really help with the management of your empire.
one major benefit are "alerts" that circumvent the need to check each city / civilization each turn for certain information - it is summarised and presented to you on each turn, and is fully configurable.
