Glad you're enjoying it. It's a mod I personally play with my friends as well... so it's tailored to that.
As for E4X, Goa the lead modder there did collaborate with during the Requiem releases, Original(JasonFJ)->Entrenchment(JasonFJ)->Diplomacy(JasonFJ+Goa)->Rebellion(JasonFJ).
I believe Goa is going to develop his own SW mod focussing on post-Endor races. There are some things I'd like to slipstream from E4X.. whadda you say, Goa??
