Yes look in the string file
( Edit )
Ok Maybe I should be more specific.
Here are the steps
1. Open My computer
{The following names are for folders.}
2. Open program files
3. Open Stardock Games
4. Open sins of a solar empire
5. Open String
{End of files }
6. Copy the English STR file. (it’s the only thing in the folder)
And put it in a safe place because if some thing goes Bad with you editing (or you just want the old names back) you can just replace the one that you edited with the backup
7. Open the English STR file. (it’s the only thing in the folder)
This is what it will look like (only a lot longer)
TXT
NumStrings 5256
StringInfo
ID "IDSPlayerAINameTech0"
Value "Nitheim Rebels"
StringInfo
ID "IDSPlayerAINameTech1"
OK now what you want to change (put the name that you want the parentheses. I.E. if you want to use the name Bob for a sun just replace Algieba with Bob)
These are for stars
StringInfo
ID "IDS_STARNAME_17"
Value "Algieba"
These are for plaints
StringInfo
ID "IDS_PLANETNAME_001"
Value "Abderhalden"
This is for TEC Cap Ships
StringInfo
ID "IDS_CAPITALSHIPNAME_TECH00"
Value "TDN Khronis"
This is for Advent Cap Ships
StringInfo
ID "IDS_CAPITALSHIPNAME_PSI00"
Value "Tyrand"
This is for Versa Cap Ships
StringInfo
ID "IDS_CAPITALSHIPNAME_PHASE05"
Value "Sultra"
But keep in mind this IS a random list so is you want only your names you have to cut the ones that you don’t want (like you make up 10 name for TEC cap ships Cut the rest of the names)
