I'd like to plug a world vs. world option in ED. Factions battling over a large region. There are diverse roles for large groups, small groups, even individual players within the combat instance. Sieges to take points, defense of points, supply protection and theft, scouting, pitched battles, feints, strategy, drama, etc. etc. This is all emergent game play based on a compelling setting and a faction reward system. Regions could be instances with megaships, asteroid fields, ground bases, space stations, alien sites. Low skill entry level players can participate in roaming zergs, experienced players take on the role of commanders issuing orders. It would almost be like the game trailers. It's great fun - but would require a central server...
