Wish is supposed to define a new category of fantasy MMORPG, which the developers call "Ultra Massively Multiplayer Online Role Playing Game" (UMMORPG). Unlike existing MMORPGs that confine players to a server with only a few hundred other players, Wish's highly-scalable server cluster infrastructure allows them to support tens of thousands of simultaneous players in a single shared world.

Every player of the game is a player in your world, and that provides endless opportunities for bonding through shared experiences. Futhermore, by eliminating the need for artificial "zones", Wish presents a seamless online experience in a world whose size and rich detail is supposed to far surpass conventional MMORPGs.
