Which worlds do you like to see in Once Upon A Time?

oooh. Halloweentown. That would be interesting. Love those movies! Anyways so, I might like to see wherever the anicent gods have been located like Percesus, Zeus, Thor, etc. I mean since we did see Medusa and all. ;) I would also like to see the kingdom from the movie Brave. Might be cool if Merida and her family are relatives of Rumple since he too is Scottish I think. I might like to see the world from "Stardust" with Yvaine the star, Tristan the prince and the three witches.
