[Dev Update] Changes to Taiwanese Accounts – 31 March 2008
New government regulations in Taiwan, which take effect April 1, restrict game companies in that region from effectively suspending or banning accounts for participating in professional farming or real-money trading. Guild Wars is highly impacted by local regulations such as this, because Guild Wars operates in a seamless, connected manner between all territories. We cannot sustain a seamless connection when we are unable to effectively police the game in one territory, because professional farmers in that territory could severely damage the game’s economy throughout the world. Therefore, we are forced to disconnect Taiwanese service from the rest of the game world as of April 1.
Users in Taiwan will still be able to participate in their international guilds and compete in international PvP, but as of April 1, they will no longer be able to enter international districts, trade with players outside Taiwan, or play in PvE environments with players outside Taiwan.
