The Nintendo World Championships (NWC) is a video game competition series, organized by Nintendo of America.
The first competition launched in 1990, touring twenty-nine cities across the United States. It was based upon its namesake custom game cartridge for the Nintendo Entertainment System, considered to be the most valuable NES cartridge ever released and one of the rarest. On June 14, 2015, the second Nintendo World Championships event took place for its 25th anniversary as part of Nintendo’s E3 2015 coverage. The third edition of the Nintendo World Championships was held on October 7, 2017 with qualifiers taking place from August 19, 2017 through September 10, 2017.
In 2014, Nintendo released NES Remix 2, featuring the reminiscent Nintendo World Championships Remix, which uses emulation and online leaderboards to incite informal public competitiveness.
