Important note:
Regarding the script of this mod, almost all functions of this mod are based on the script. However, most complex scripts are manually executed functions, such as merging species. There are also some high energy consumption automatic scripts that are turned off by default and need to be turned on manually, such as the automatic fleet merge function. And all automatic functions, such as trade optimization, habitat restriction, and automatic migration, use algorithm-optimized scripts to minimize computational overhead, that is, these scripts will not cause performance impact.
Please check the instructions for each option to decide whether to enable the functions that are turned off by default, or use the default state to get the best optimization.

Work together with Industrial Revolution

For Japanese Translation


-Reduce the number of ships: small ships are merged into large ships, which is only effective for ordinary empires and fallen empires, and may affect AI behavior mode. Use it with caution
-Species integration mode: Combine similar species into one species according to the species category (organic/stone/mechanical) and the integration of civil rights (random selection of templates)
-Targeted integration template: use a species as an integration template by adding features or make it ignore integration
