Oh, and continuing my faction music subtopic, I would like to have combat themes more varied, as the Terran war theme used in this role for majority of factions may quickly get old. For specific combat tracks, I would like to point to the unused GC3_Drengin_War.2.mp3 file (an alternate Drengin war theme I've heard in the combat beta test video by IGN) and suggest using a track borrowed or derived from Star Control: Origins for its respective DLC races. And of course, please fix typos in the music definition files (as well as everywhere else if any)! The Snathi's declaration of war on me during one of my playthroughs was silent.
(By the way, an examination of the sound bank using Dragon Unpacker revealed that the sounds are in Ogg Vorbis format, but I tried using Ogg files for music and it didn't play — it only supports MP3 music. I would welcome adding support for Ogg so modders won't have to put music quality at risk while transcoding their Vorbis tracks to MP3.)
I would really like to have the old campaigns (and the tutorial) adapted to the reality of Crusade and Retribution expansions. A newcomer would be confused with how to play the campaigns under an archaic gameplay. By the way, recent Sid Meier's Civilization games have a drop-down list which allows to choose which expansion's rules of gameplay will be in effect, is there something like that considered for GalCiv3?
Will there be any improvements to the technology tree system? Is it really possible to recreate GalCiv2's configurable civilization-unique trees and don't have such nonsense as the Phamysht having access to the Shrine of Tandis (which is supposed to be an Altarian exclusive improvement)? Also, I think that would be useful for the campaigns (should be they updated), as this allows to disable out of place technologies like the hypergate, which is only invented during Retribution's time period but appears quite early in game.
UPD: And can you please make the Theocracy government from Intrigue require the Devout trait instead of Bureaucrats? It would make more sense, and Mowlings would praise Jeff for eternity if you do that.
