There are 5 Mass Drivers on Earth in the Cosmic Era, right? Those 5 places would end up being places for trade routes to Lunar Base and the other L points., but make it that Earth Forces cannot send their forces directly to attack ZAFT from Earth without going through other areas (the whole 'skip' thing. most worlds would be empty space to move your fleets around.)
If possible, we arrange some of the planets into some sort of sphere, maybe 10, modify the planetx to look like a part of Earth so it looks like a shell (if possible). 3-4 planets on Galactic map would be the Moon (Plotemalus Base, Deadlus Base and Endymion crater as example maps) 5 planets would end up as Lagrange points.
ZAFT starts out with one planet (which would BE L5, and instead would be the 120 PLANTs as background). Possible land maps, likely not for the PLANT map (unless you give the EA 'raid' ability to do covert missions against ZAFT. Alternatively depending on tipe ZAFT has 3 maps, one for the PLANT and 2 for Boaz and JAchin Due. (effective examples for nuking with Blue COsmos)
Other Lagrange points would, depending on when you want the game to begin, either the original Nova, Artemis, ZAFT HQ, etc or later on, there would not be Nova, possibly Heliopolis and instead there are 2 Space Stations at the ZAFT 'world'.
Landing ZAFT forces would be drop pods or deploying from aircraft on Earth. Reinforcement points would have larger radius. ZAFT can have Nibelung as 'Bombing run' but it is expensive to get and research.
Earth Forces deploy their ground forces likely from aircraft on Earth. If EA sends troops into space, they could function as other ships, training instantly to be new crews which are transferred to spaceships.
Earth Alliance and ZAFT research, but likely the EA should be able to steal tech from ZAFT, as they did do that in the first war capturing some GINNs based on GS novelizations.
Likely only ZAFT researches.
Earth Alliance Superweapon would be Blue Cosmos Fleet, 4 Agennomons that would have a countdown until firing range to launch Mobius to nuke the ZAFT (with the "FOR THE PRESERVATION OF OUR BLUE AND PURE WORLD" quote when pressing button haha. Built after N-Jammer Canceler is developed and only able to be used in space against ZAFT stations/background.
If ZAFT is not able to build space stations, the Boaz and Jachin instead they would be background using the 3 maps version, allowing them to be nuked.
EAF forces can only build Space Fleet at Lunar Base including Mobiuses, however The Earth Forces can build Mobile Suits and send them up to space later on.
Drake-class warships can have second weapon-missile stream against Mobile Suits. Decimates enemy Mobile suite or distracts them.l Either one-time use or long recharge rate. Nelson's secondary weapon is increased fire for a time, Agennomon's ability if to launch Mobiuses of Daggers, depending on tech tree and/or to rally EA forces.
ZAFT warships likely have weak shields that do not recharge to be the whole anti-beam coating on ZAFT.
Nazca's secondary option could be to have increased fire or to launch other Mobile Suits. Laurasia's secondary ability is to.....uhh any ideas
Gondwana's secondary ability is to launch Mobile Suits as well.
