Im No modder, but i have an Idea....
Like i said im no modder, but maybe someone who is could possible use this....
Sides: SGC Aliance (SGC, Asgard, Tokra and Jaffa resisance)
The Humans and jaffa, are the ground troops where the Asgard are the ships and the Tokra the Spys
System Lords (the last of the gou'ld that form an Aliance to Survie)
And possible other sides, if someone takes up this.
