The reason this map was removed was cause the community hated it, and the community hated it cause it was too damn big. And what do you get when you play on a map that's too damn big? A map that runs through an entire game and is extremely boring to play on.
I can only see Hungry Hills returning if the map was made a little smaller, and if it was only implemented in 48 player servers. It's a beautiful map, just not fit for 24 people.
EDIT: Oh yeah, didn't see the part on Asia Games.
The reason the Asia Games is so liked is cause it's packed with interesting stuff, and isn't totally boring. Hungry Hills barely had any landmarks, and people HATED the giant hills to get over things, and especially back to the cornucopia.
