Yep! If you have the ships and stations, you can make the faction.
Yeah. This could be excellent.
Now, I haven't yet taken a look at how this is configured, but Schine should definitely think about having custom factions be able to be confined to a single folder within the factions folder, so they can have custom configs for them specifically, with subfolders in turn for things like their blueprints for ships, stations, etc etc
This would make exporting a well-designed faction a breeze.. and wow wouldn't that just be rad. An "Imperial" faction with Star Destroyers and boatloads of TIE fighters? With some serious aggression tuning in the config..
Just, too cool. Too much fun, stop it!
