QuizQuiz (Korean: 퀴즈퀴즈), also known as Quiz Quiz, was a massively multiplayer online (MMO) quiz video game created by Nexon which used a super deformed type anime graphical style to portray the players and the few environments or non-player characters (NPCs) it contained. The game was released as a free beta download off of the Nexon Inc. website but was later discontinued in North America due to low playerbase. Released in 1999, it was one of the first free-to-play games using a microtransaction revenue model.[1] The game remained available in South Korea, Japan, and Singapore but the Singapore and Japan servers were later shut down as well in December 2004.
