Since I've started playing this game I've always wondered if it would be possible to create a multiplayer map of a scale Earth's Sphere from Mobile Suit Gundam:
Basically as the image implies it would consist of the Earth, the Moon, seven Sides* and four large asteroid bases (Luna II, A-Boa-Qu, Solomon, Penzun).
*A side is a cluster of O'Neil cylinders numbering around 10-20 colonies in each side. Each colony is 6 km in diameter and 20 km in length.
This map would require a TON of work of course, besides the basics listed above, you would have to create the bases, cities, and interiors to certain buildings and bases. Plus everything is huge in the Gundam universe, a mobile suit (a fancy name for giant robot) average around 18m and the ships that carry them dwarf mobile suits.
Mobile suits would also have to have an overhaul, I imagine if we do get mech leg parts they will be pre-fabs and probably mech warrior style legs. So a mobile suit would probably not make it to canon sizes.
Another issue is scale, what would be the right scale? 1/1 is out of the question, I don't know how, and if ever the game could support a multiplayer map with 1/1 earth, colonies, and asteroids. Plus at that size things would be pretty empty. A smaller scale for the earth, moon, aasteroids and the like would probably be preferable while keeping the canon vehicle sizes.
If this could be realized then it would make for a fun map, especially if a group could re-enact the war from the show. (Nuking Sides, dropping a colony on Sydney, Australia, converting one of the colonies into a giant beam cannon, massive battles)
