Well, I've once had an idea to suggest making sol system in the destroyed form and adding it to the mod. 1 jumphole leading to a cloudy, lifeless, Newcastle-like system - transit, so that noone wanted to visit too often and at the opposite end of it, another jumphole or sereies of jumpholes, leading to various regions of Sol. And depending on if we acknowldege the official or extended intro, there would be good looking, populated and dockable planets or decimated, sometimes in pieces and non-dockable.
The storyline itself should not perhaps be as revolutionary as FL 2, after all, this is a mod, not a separate release. Besides, I bet we'd have legal problems when we'd name it FL 2. However, imo, it should develop constantly. For example: Kusari-bretonia war ends, Tau-31 made into a DMZ, both sides accept a mutual white peace and complete the trade lanes inside te system as well as a new jumpgate. BMM outpost in Tau-23 gets taken over by IMG, which funds a trade lane between it and Java. Really, I'd love to see more infrastructure in places like these.
