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.
This is the Arc Hammer and its escorts. In the new X version developed specially for the Steam, Gold and GOG versions from the game. There will be many battlegroups like this.
This version will be released clearly before end the month and at first place, it will be a addon for the next 7.3B full.
The 7.3B full will be recomended only for the first version from the game, the version with 2 DVDs and if you run it in the Steam, Gold or GOG games, you will be alone and as always under your responsability.
So, if I am understanding this correctly, in the future there will be separate versions of the mod that are specially designed to work with the disk or digital versions of the game respectively?
Yes. Exactly. At a first place, it will be a patch but in a future, they will be separate version because even if the X version can add some new features, the features which they do not run in the Steam/Gold/GOG versions are very good and many people like them.
Other point are the campaigns. The scripted campaigns do not run without problems. The X version, at least at a first moment, they will have not them. Perhaps in a future, I can remake my new campaign for them. But clearly, I will not make the original EAW and FOC campaigns because they will not run without problems at a million of years. In fact the last time that I worked with them, I played with the Steam version and I moved to the normal 2 dvds version because I could not finish it.
