the player has to be 2 days old or more I think, and neither of you are allowed to have used his/her name before. Those were the only requirements I've found and so far I've done this quest on 3 characters
A couple of the bugs seem to have been sorted, and the descs on the site have changed. (Riddle Master and Really, Really Well Liked)
Managed to recomplete Riddle Master after Sadistic Coach by dropping the ball as it suggests - previously the cub guarded so the only way out was by attacking a sphinx cub. This naturally makes Misty love you
Trying to have Really, Really Nice regranted is a pain...eg there's a time limit as to how long you have to wait for another alphabet game and the said pieces of ex-husband don't seem to be helping. Does anybody know what 'valuable things' she likes?
'If she doesn't, you may have done something to make her dislike you. In that case you can gain brownie points with her by giving her bits of her ex-husband, and playing games with her. If that doesn't help enough... she also seems to like valuable things.'
Unless they closed it, thats the only way to get in. I remember making a newbie alt and it wouldn't work, maybe you actually need to be able to hit him to manage it or something. After I advanced the newbie a bit I got it working.
