Well personally I am in favor of starting a new area for new Star Wars stuff, but I must add something of importance. That is the SVN. We have a database to start building on. I put something up just to get started on something, but I am busy with other mods at the moment. I can always help a little though if someone steps up and wants to work on it.
The things that still need to be worked out in my opinion are.
The first thing is the map. What should be used? I started with the Final Frontier mod. I would like to see it modified to work, but if someone has a better solution great.
The second what will be the setup? Is this a scenario from the movies? I would say not to stay with all of the factions from the movies, but instead go with Star Wars history starting around the time of discovering hyperspace. So it is more like civ in space.
There is plenty of info on Wookiepedia for techs in that case. I would just have is the civs as planetary systems. Not the factions from the movies, but the possible of making factions later in the game. And adding scenarios like from the movies later.
But either way unless someone shows interest that can modify the SDK for some major changes it is stuck in my opinion. So I am all for starting up new, but I have not seen anyone really getting anything done recently.
