Give players something to fight over in the sandbox! Give us some locations that players want to fight for control! Let players earn reputation or credits or both for participation. Don't go the route of every other MMO out there! Go play WARDOGS for a day to see how FPS is done well and how vehicles are incorporated with logistics!!!! Note that the game has full-looting, and there is a harsh consequence for dying and giving up as you lose your kit. But also, there is ease of access to get that kit back and rid, drive or fly back to the action. In my opinion, distribution centers could be an ideal location that multiple factions fight over. With a little bit of logistics and base building opportunities... man! The emergent gameplay could rival wardogs!
