Someone in my FC recently had the idea to give us a little riddle and I liked that so much that I'm now spending quite a bit of time myself creating riddles for the FC!
I always liked the riddle-type quests in the game and was quite dissappointed that we never got such a good one as the ARR-one again. But I can understand that riddles are a lot of work and that probably not enough (or a lot) people did that quest to begin with...
But hey, if the devs dont give you the content you like - try and make it yourself! ;D
(It would honestly be great to get some tools for this type of thing - like being able to leave notes or something in the world... give NPCs lines of textes... I know that thats not possible, but a girl can dream! Right now I'm trying to find ways to work around that to be able to do more complexe riddles... keeps you quite busy and I enjoy it very much - I just hope my FC does aswell!)
