First, I want to thank you for replies! I will try to give you more details about who we want to be and what we want to do.
We must to admit previous reputation tabel was not set up correctly, so it was adapted, to reflect properly diplomatic relationships with the most important factions (for us).
So... let's see! Though we are traders with origins in Liberty, Liberty Trade Shipping corporation is not settled there. I know... sounds weird, but the idea is that our group wants to be identified in a different way, in comparison with other corporations located in Liberty. As you can see, we have headquarter in Kusari space and our main goal is clear: improving trade relationships between Liberty and Kusari, and this will not be changed!
In the same time, in all our actions, we will not disown our origins. We are not freelancers or any kind of exiles. We just want to be perceived as traders and nothing more. Is true... we have Interpace Commerce ID (and IFF Interspace), as long in game, does not exist an "Trader ID" or something similar. But... we would like others to understand, that we are not the same thing with Interspace Commerce (player faction)! They have different conceptions... eh... that's another subject and I don't want to deviate...
As we have noted, is very difficult to set a perfect line for all factions (NPC's or player groups/factions). This is because some of these relationships are not exactly in accordance with the facts. Maybe for this reason, the most of the player groups or factions, when announce their diplomatic relations, prefer to limit themselves just at essential ones and we decided, in the end, to do the same thing. There is a mismatch between reputation that you can set in wiki and the one you can have, in fact, in game. For example, if we set -4 lines on wiki for a faction, this will become "Unfriendly". But in game, if we have -4 lines with a faction, this will remain "Neutral". I hope you will understand what I try to explain you.
Anyway... starting from the idea that we are only traders and our group do not wants to be directly involved in political conflicts, one of the most important goals is to keep neutrality with local authorities from other houses and to have, in the same time, cooperation agreements with some trade corporations, even if these are located in houses that are not too friendlies with Liberty space. In fact, our dreams is to build a distinct position for traders, in generally, but unfortunately, it is obvious that is very hard or maybe impossible to be put in practice, as long we belong to one of those houses.
So... here comes one of the most interesting parts of our story. We are from Liberty but we do businesses in Kusari. Nothing wrong so far, if we will respect local Kusari laws. But in the same time, we want to do businesses in Bretonia. Well... here comes the first issue. You know very well what are the relationships between Kusari and Bretonia. We think the only way to do businesses with Bretonia is... via Liberty -> Bretonia, and with Kusari, via Liberty -> Kusari.
Anyway, I hope you will help us to determine, in future, a more complex and realistic reputation sheet. But now, is enough to limit our public relationships only with groups and factions from Liberty space.
Any suggestion from you is welcomed and all constructive criticism is appreciated!
