Wish

Wish is a game that allows millions of gamers to interact and share fantasy adventure together. Unlike other online games that only allow a few hundred players on one server, Wish defines a new category called UMMORPG (Ultra Massive Multiplayer Online Role Playing Game), which provides a highly scalable server that lets tens of thousands of players share a single world. Every player of the game is a part of one world, and that gives gamers the opportunity to bond through shared experience.

Wish will begin a limited closed beta test in December of this year, and increase to 10,000 players by the beginning of 2004.
