most mods have extended the list or added new ones

To quickly find out what mods have for unique

you can look at the techarea.txt

and any tech area that has the unique area such as
Name := Neural Computer Interface
Group := Applied Science
Description := Advanced computer interface which connects ships during combat.
Maximum Level := 1
Level Cost := 30000
Start Level := 0
Raise Level := 0
Racial Area := 0
Unique Area := 3
Can Be Removed := False
Number of Tech Req := 0

and if you read the description for the unique area you get this

Unique Area:
This is a user-defined number which is connected to certain abilities such
as Ancient Ruins Unique. Some abilities will cause a unique tech to become
available. If this number is greater than zero, then this technology area
will only be shown to the player if they have the attained\activated the
ability with the corresponding Unique Area id.



Hope this helps
