I use to have this big text file that had quests upon quests laid out for iClassic. It was broken down and modularized for release. The only bad part is that each of them can be occupied by one player at a time unless we come up with some sort of level duplication system. Which is a possibility and would be awesome. If we could find someone with time to do that.
But either way I have some (I think) neat quests that are sitting at their beginning stages. They just won't work with the sheer amount of players we have.
