Heres my thought.

Take the most popular games[Gaia,Neopets, xbox,etc] And have a certaint lotto.
Such as, For example, On neopets buy a ticket for 500 lg gold, and a item is the pot or neopoints.

Yes, i looked at someone else's thread. But, i do think this is a good idea.
As far as xbox[i dont know much about it] maybe an item for a certain game everyone plays?
