Pokémon World Online, or PWO, is a beta game played on the computer. It was created by Kyrocorp. It's first beta release of the game was Decmber 27, 2007. The game uses graphics based mostly on Pokémon FireRed and LeafGreen, as well as some parts of Pokémon Emerald. PWO's website is http://www.pokemonworldonline.net/.
Registration
Due to their poor servers, PWO staff can't handle registration being permanently open. They limit registration to a few hours a month. That's why there are only about 12,000 players, and the server holds 450. I HAVE A GIANT SCHLONG
