Have an idea that might be neat.
Drop a planet in Rift blue. Start it as a dead world. Then the entire server has to terraform it up to gaia V.
Then hold a vote on forums or in game on what to name it. Could name it after old players/corp or someone that died or Planet McPlanetFace, whatever. lol.
Once it hits gaia V. Move it out to a corner of the map on a neutral, can't be busted, garrison. Could have it randomly be moved around map every once and awhile. Have rewards issued for terraforming it. Would be a pretty good community event.
Could do the same thing with a random planet/garrison deployed in black somewhere off of Grey boarder. This way new players could have access to a gaia if the whole community puts work into it.
For black could do similar event where you drive out to planets parked on corners of maps. When you get there you pick up a load of colonists and bring them to earth to upgrade its ship yard.
