Hi Gekiganger!
I see you there! 😀
It was quite some time since I last played X4 but you have two options for the relationships.
You can change what the factions think about you and what "you" think about them. If you go into the negative values that means that you/they hate you/them.
For example, if you set Criminal to 1 they will love you or you will love them (depending in which field you edited it)
The max value is 1 as far as I know and the lowest is -1.
I hope the above helps.
King Regards,
Ben

Ok, that makes a lot more sense than what I had initially thought. I was thinking that it was somehow tied to reputation. Thanks for the clarification.
