In old school MMOs, devs would do things like this and we LOVED IT. There was an enormous saga in asherons call where PvPers on one server fought defending the enemies, which stopped the story from progressing. Of course, they wouldn't have the story out of sync on one server from the other 7, so the entire community sat in suspense watching. It lasted weeks. They had to have outside mules bring them spell ingredients, foods, etc. This event stuff is awesome, it's just been wasted on the most shallow generation of gamers. But alas, video games have been infinitely dumbed down. And worse, gamers have been even more dumbed down to the point that when a dev tries to implement something similar, and to a much lesser extent, they whine about it and accuse the Dev of withholding content.
