Okay, so here's what I had in mind... Bear with me here...
An Earth similar to our own, one of many parallel and alternate Earths. A twin of two, split apart long ago in time and space, by an unknown force. Neither truly knowing of the others existence, except for handed-down knowledge among a handful of curious and driven individuals who believe that the secrets of the past are the key to a better future for everyone else - no matter of what the truth may actually be.
The members of these groups, on both Earths, manage to make contact based on the technology and information culled from the ancient remnants of the Precursor race. They also discover that they have left their genes seeded throughout the populations of both worlds, in the form of those who possess 'above average' talents and skills, and especially those who are supernaturally gifted in mental abilities. These individuals, they call 'Composers', for their ability to enhance their skills and abilities through the use of music, often specific verses and tunes left by the Precursors.
The organizations recede into the shadows of history, but are always there pulling the strings, and manipulating events to their own goals. Some groups have some idea of their existence, but never anything concrete. They name themselves 'Elysium', for the belief that the united world will be an idyllic paradise.
On both worlds, history continues. On one Earth, history mostly followed the same course, although the Cold War went hot in the late 1980's-early 90's after the Coup in the Soviet Union succeeded. This lead to an increased level of scientific development, and greater colonization of space and accelerated development of technology. Advanced computer technology, weaponry and robotics lead to the development of walking robotic vehicles in the latter half of the 20th century, with full deployment in the early 21st, after the end of the war and the following peace and numerous civil and brush-fire wars that broke out.
Throughout the later years of the war, and the early 21st century, an increase in strange and paranormal events was recorded, by soldiers as well as by civilians. People observing unexplainable events on the battlefield; strange or unearthly creatures, or seeing unfamiliar surroundings. And often accompanied by music in their heads or elsewhere. Initially, it was confined to one or two persons, but then whole groups and units began experiencing such events, meaning there must be some substance to these claims. These were part of efforts by Elysium to use their Composers to break through the walls of reality, and establish permanent crossing points with their counterparts.
At the same time, side-stepped from our reality on a parallel world, similar events occurred. Many events were similar, and the geography much the same: only the names were different.
On this world, instead of humanity a multitude of humanoid, animal-like beings evolved, or perhaps were engineered by the Precursors.
As they developed on their separate world, they arrayed into loose power 'blocs'. A number of similar wars broke out, through the manipulations of Elysium on the various governments. Using Composers in battle, and also harnessing the use of the GEAR - the same walking fighting machines as used in Earth's wars - the Elysium-lead forces come to dominate the majority of the battlefield, and in so doing become known to the remaining governments, who have banded together.
The main reason the United Forces are able to hold back Elysium, is due to their gutsy GEAR pilots and associated forces. Originally members of the armed forces or other paramilitary or Law Enforcement groups, they have become an assortment of freedom fighters in their array of customized and tuned-up bipedal walking fighting machines.
On the other side of the barrier between worlds, Elysium is looking for the same thing: Composers from the human world.
A small array of individuals, head-hunted from both exhausted superpowers, East and West, are recruited into a covert unit to hunt down Elysiums operations and find out what they are up to. Made up of soldiers, pilots, investigators and more from all areas of military and paramilitary backgrounds, they are also selected for their personality and aptitude, as well as open-mindedness and willingness to work with potentially former enemies.
As they get deeper into the mystery of Elysium and their activities, the truth becomes apparent: there is more than one world, and Elysium is blurring the boundaries of both.The revelation comes too late though, as Elysium on both sides have assembled Composers, at strategic points of convergence around the globe. As they launch into action, focusing their powers through the use of ancient music and words along with technology, the worlds blur together.
With their being reunited, the two worlds are also reunited. Elysium's manipulations come to a head, and with the ancient technologies and sites reunited, they come into their power, and begin an all-out assault against the remaining governments, who are reeling from the impact of numerous wars and attacks in their recent pasts, as well as the environmental disasters caused by the merging of two planes of existence.
All around the world, people are reeling in shock, coming face-to-face with aliens (on both sides) and legions of unknown enemies equipped with powerful technology.
The Elysium forces have a final goal - locate all the remaining Composers, and gather the remaining Precursor devices and knowledge. For what goal, the remaining free forces do not know, but Elysium are more than willing to dominate, destroy and otherwise roll over anyone they don't consider worthy of being part of their elite - which is, essentially, everyone else.
Furthermore, the two worlds are not harmoniously bonded, numerous areas are ridden with dangerous geological or spacial faults. Areas overlap incorrectly, and there are things at large. If the two worlds are not separated, then both may be destroyed.
With so much to take care of, and both races threatened by the plans of Elysium and the alliances they have made, the leading anti-Elysium governments of both worlds form a shaky and hasty alliance to put their people together to find out what Elysium is up to, and to try and stop them. Their operational team are equipped with their own custom GEARs and mecha as needed, and the best equipment available to fight back. The group is a rag-tag bunch, but they're the best, and chosen for the quality of their character, as much as their skills.
The story will be one of mystery, adventure, and will involve big epic (in the true plot-related and classical sense of the world not 'lol teh epic' sense) moments and concepts, relating to the destiny of two worlds and their eventual fate, and their origins to boot. And how a lot of that ties into the origins of both species, and the wider universe and life itself too. Basically, all the great stuff that comes with a proper epic 'real robot' show.
It would have recurring villains and a nemesis for our group, who would be a mix of human and anthropomorphic characters, and they would have a variety of mecha; though they would be closer to those of GEARs than Macross - but transformable ones would be part of that group as a possibility too.
Characters would need minimal edits, just background changes (in my opinion, anyway) and if people wanted to change them that's possible too. And if you want your old mecha from GEARs back, then go ahead too.
If people are interested in this idea, I'll post up world details and the like. Leave me opinions, and let me know what you think. Ask as many questions as you want - really, I'd be glad to just see some activity, since things have been quiet.
Likewise on the alternate Earth,
