Dynamic events based on the rotation of the planets in the solar system. Invasions of other planets that have survival elements (hostile invironment, climate and seasons) in it, and if you want to bring back resources, require lots of mounts, carts and wagons... so group/guild effort. Sounds much better then the usual grindspots and gathering in other mmorpg's. Below you can see how real time stand the the ingame day/night and seasons. For more info check out the dev blog below.
