What comes after the emerald quest?

I have the emerald quest and a friend has completed this quest she had a few little quests after and now she hasnt got any do anymore appear of is this it?

The emerald quest is the last quest, if you have already completed the UFO series.

I completed the UFO series and the emerald quest, but when I look at "Player tops Quest Performers" tab of Ratings, the most players (including myself) have completed 392, but top 6 completed 432 ~ 435. Does that mean I still have 40+ more quests? or am I reading the chart wrong? If someone could answer it, I would really appreciated it.

I wouldn't pay so much attention to the Rankings. Honestly, I don't think those are attainable numbers. Perhaps they are game testers. I started in January as the holiday quests were ending. I don't think there were 30+ holiday quests.

One of the top 3 Questers is my friend, and she isn't a game tester. She started playing from the very first day it was launched (since she was a Facebook player so she was excited to see it on iPad).

Some quests go by very quickly that you don't notice them. A quest to find 1 of this. Another quest to find 1 of that. So for 1 collection, there can be 5 quests. Another quest to charge the whole collection. There were quests for banishing various types of elves, and other quests about Christmas trees and ornaments and toys. There are 8 Christmas collections, so the quests could easily total to about 40.

thank you very much for the both answers. it makes sense. I also started playing after the holidays. Now I just hope that GI will release a new update with more quests

Thanks for the clarification, pianofingers!

I guess that means the oldest players, as long as they keep doing all new quests, will remain on top of the list.
