In 1998, Gameone completed the strategic role-playing game "Warlocks" in less than a year's time.

It is the very first Hong Kong designed and produced game to gain such widespread popularity in the Southeast Asian region. In addition, TGL, a leading Japanese computer game manufacturer successfully launched the game's local version in Japan. This made Gameone one of a handful of companies from the Greater China region to successfully break into the Japan computer game market.
