Again, not having seen the show, just reading what you guys have posted about, parallels with Gall Force seem more obvious.
-Age old constant cycling conflict with the Solonoids (biological all female race) & Solonoids (bio-mecha male race) that almost always results in a complete whiping out of both, with an eventual union of both (then subsequent seperation restarting the cycle).
-Catty, the secret android ally, turned enemy, but really an ally who pops up through subsequent generations of characters.
-The last survivors of Eternal Story Progenate the human race on Earth, and despite leaving behind all previous technology, humans later stumble upon Paranoid reckage (I think on the moon), use it to engineer new AI, which results in an all new conflict, which eventually leads to the destruction of Earth & the setting out of what would likely become a new Solonoid faction (leaving behind an AI/Paranoid faction) etc.
Sure Gall Force at first glimps borrows a lot from Macross & Alien, but its original story elements seem to be the major backbone for this new BG.
