Kru Interactive (spun off from Nexon Co., Ltd) is a company that operates and manages online gaming and MMORPGs.
The company has recently expanded into other Asian countries, notably Japan, Malaysia, and Singapore; along with the United States.
Nexon has also released a few unsuccessful games to the North American audience in beta form which have since been dropped.
QuizQuiz never left beta stage in North America but was later released through the Singapore division of Nexon, NexonAsia in an English version.
QuizQuiz has since evolved into the exclusively Korean and Japanese online game Q-Play, while Elemental Saga was eventually cancelled.
