Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
To avoid misunderstandings...............I have added this piece of information written at red over the box the Total War setup options showed in the begining of the Galactic Conquest.
About the 7.63X progress, the Rebel campaign part I is finished, even I have added a lot of additional missions. Now I am thinking if I continue adding more parts or I release the mod in Steam. I do not go to release it for other game than Steam. The point from release before end all the campaign, it is how I will need a lot more of time and I can update the files at Steam very easily with each new addition.
That explains a whole lot actually, I always wondered why the ai seemed broken with all factions enabled.
