The World Electronic Sports Games (WESG) is an international esports competition held in Shanghai and organized by AliSports. The first event had a total prize money of more than US$5.5 million, and its final matches took place in December 2016.

The WESG is inspired by the Olympic Games. During the first three years, teams were required to include only players from the same country to highlight the pride of being part of a nation. This rule led to some national teams being created only to compete in WESG. For the 2019 edition (and possibly later events), this rule was changed to allow teams to include up to two players from other countries. The event also features separate competitions for men and women. Most tournaments use a single-elimination format, where a player or team is removed from competition after one loss.

Games

The following games were included in the event. In 2017, WESG added female tournaments for Counter-Strike: Global Offensive and Hearthstone.
• Counter Strike
• Dota 2
• Hearthstone
• Starcraft II

Tournament history

As of March 2016, the qualifying rounds for the first edition were expected to begin in April 2016. The event was held in Shanghai.

Despite the large prize pools, many top contenders were not at the event, especially with CS:GO's first major of 2017 approaching. WESG 2016 for CS:GO was the last major tournament before the ELEAGUE Major 2017. France's Team EnVyUs defeated Poland's Team Kinguin to win the majority of CS:GO's largest prize pool. Poland's top team took third place by beating Turkey's Space Soldiers and qualified for the Atlanta major.

In Dota 2, the Filipino team TNC Pro Team defeated Denmark's Cloud9 to win the grand prize. Sweden's Alliance beat Peru's Infamous to take bronze.

In Starcraft 2, Korean players dominated, as Jun "TY" Tae-yang defeated fellow Korean Cho "Maru" Seong-ju. In the third-place match, American Alex "Neeb" Sunderhaft beat Germany's Tobias "ShoWTimE" Sieber.

In Hearthstone, the Philippines' Euneil "Staz" Javiñas defeated Sweden's Jon "Orange" Westberg in the grand final. The third-place match featured two German players, with Raphael "BunnyHoppor" Peltzer beating Sebastian "Xixo" Bentert.

Even though it was called WESG 2017, the event took place in March 2018 in Haikou. In CS:GO, more top teams attended compared to 2016. However, teams like Brazil's SK Gaming and the U.S.'s Cloud9 were eliminated early. Teams such as South Korea's MVP PK and Brazil's Team One, which had not qualified for the major, advanced further than expected. Sweden's Fnatic won the WESG 2017 title after defeating Turkey's Space Soldiers.

In the third-place match, Russia's team stopped Team One's progress. In Dota 2, Russia's team defeated Brazil's paiN Gaming. Greece's Team Hellas beat China's Rock.Y in the third-place match.

South Korea dominated Starcraft 2 again, as Maru won the title after defeating compatriot Park "Dark" Ryung-woo. Finland's Joona "Serral" Sotala defeated Kim "Classic" Doh-woo in the third-place match.

In Hearthstone, Turkey's Kaan "Fujitora" Çekli defeated Canada's Michael "Luker" Luker to win the grand prize. Japan's unknown player, posesi, took third place after beating Thailand's Kantaphon "ScreaM" Suwanmalee. In CS:GO's female grand final, Russia's team narrowly defeated China's LLG Gaming. In the third-place match, Canada's team beat Sweden's team. In Hearthstone's female grand final, China's GLHuiHui defeated Lioon. The UK's Cordelia "Scarakye" Chui lost to Hong Kong's Ip Yan in the third-place match.

Even though it was called WESG 2018, the event took place in March 2019 in Chongqing. The WESG 2018 tournament began only a week after IEM Katowice 2019, the first CS:GO major of 2019. This made it difficult for most top teams to participate. Only G2 and fnatic, who had not qualified for the major, and Brazil's MIBR, who had reached the semi-finals in the major, attended. MIBR faced jetlag and was eliminated in the quarter-finals. In the semi-finals, Poland's AGO defeated fnatic, and Windigo defeated G2. France's G2 won the third-place match. In the grand final, Bulgaria's Windigo defeated AGO to become champion. The prize money of $500,000 was distributed more than a year after the tournament ended.

The 2019 event was planned for the first quarter of 2020 in Chongqing but was postponed due to the COVID-19 pandemic. Some regional qualifiers had already occurred. In 2019, the one-nationality rule was relaxed.

As of June 2023, the tournament has not been officially canceled, but no announcement about its future has been made.
