Yes, but firstly - this is the wrong forum - should be in general editing forum

Okay - you need to change initial_world.ini file. There the game sets EACH factions reputations with each other up (FIXED) and how they feel to each faction (FIXED) for when you start a game. So - if you go in there and change a few values - you will have it done.

Here is Liberty Navy

The bold line is how they feel towards Rheinland navy. They like them....

Okay - compare it to the Rogues - who they dislike:
rep = -0.65, fc_lr_grp - so you can see that -ve means dislike, +ve means that they like, and 0 means neutral. So - to make liberty navy and rheinland navy attack each other, you will need to make them hate each other. this is done by making them both negative with each other (so that bold line above should be -ve) and then go to rheinland navy and change there too.....

Make the highlighted entry -ve as well. That should get you moving. You will require to start new games and stuff for it to work (or use your own server). I must admit- i haven't actually tested this personally - but logic dictates that this will work

Thanks for the information it will really help when I start a new game, I am actually trying to change how NPC's react to each other with a game in progress. I have completed the campaign and I really dont want to have to start that over again.

Thanks

You cannot do it. Its fixed as the values in the initial_world.ini file - mainly as if teh liberty police were killing lots of Xenos instead, then they would not kill rogues suddenly.........they would end up chums with all the pirate factions - which as you can imagine would be ridiculous..............

They cannot change the reps with other factions due to the actions of NPC's.....sorry.

Empathy.ini ONLY changes the players stats dependant upon your own actions, once again, the NPCs cannot change how they feel towards each other. If you think about it, what would happen??? Eventually you would need dynamic changing of their ids information upon who they dislike (not possible) and they would end up loving some crims, hating others, and generally making the game a big pansy place full of neutral feelings
