We have completed several meetings where we addressed issues we'd discovered in the quest system. In attempting to give players interesting quests that tie into and are influenced by their past and that work with their personal story, we were running into several problems when it came to players grouping up for these adventures and then having the leader of the quest leave during the adventure.
We have now solved the issue and believe we have a quest system that will handle both personal quests and group quests for the player. This is an amazing quest system the likes of which no MMORPG has ever attempted in the past (due no doubt to having to solve the same issues we went through). But, we have it designed now and plan to start implementation of the Quest building tool fairly soon.
