Any chance of this mod coming to rebellion soon?
Soon? Probably not. There will be a fair amount of work involved. When/If I get around to converting it, it will likely happen in phases. There will be a "beta" of sorts that is basically the mod, as it stands currently in diplomacy, that will run in Rebellion. There will be no "Rebellion" features (titans, etc) but it will work in Rebellion. Phase 2 would be converting certain ships, etc to use the new Rebellion features. For example, the Atlantis would become a titan, as would the Galactic Colossus and Sovereign, etc. This will require a some thought and planning as I will basically have to redo abilities and add some for them to be titan-esque, which is why it won't happen in phase 1.
That being said, I have not been doing any modding at all for some time and I have barely touched Rebellion as a game yet. I will have to find the motivation to get to this. I will likely be taking holidays over the course of July, so if I find myself with the inclination I may have the spare time to get phase one completed then.
