"Some people say Trump is bringing the world to its end, but I think he's playing a positive role when it comes to China, " said Chang, a grey-haired executive who prefers jeans to suits "He's speeding up China's change through pressure."
Chang could also use the money: WeMade now relies on royalties from licensed games like Mir for half its revenue.
On its WeChat account on May 10, before the arbitration court's ruling, Kingnet said that although it was open to negotiations, the damages WeMade was seeking were too high. It urged the South Korean firm to stop "ill-intentioned" lawsuits and "unreasonable" demands. Tencent didn't comment, while Kingnet and 37 Interactive didn't respond to questions.
"We fully respect the intellectual property rights of others and of our own, and we are a constant advocate for the protection of copyright," NetEase said in an emailed statement. "NetEase has always had a 'zero tolerance' policy toward copycatting/plagiarism."
Even before the trade war, Chinese courts had begun enhancing protections for intellectual property, as more domestic corporations climbed the value chain and produced cutting-edge innovations. But Chang feels that's accelerated as Trump called attention to the issue.
He hopes winning more suits will boost profitability. Still, the effects of court battles like his could be felt beyond videogames.
"It would embolden more foreign companies, especially ones in the U.S. and Japan, to go ahead with suing Chinese firms on Chinese soil," said Wi Jong-hyun, a professor of business management at Seoul's Chung-Ang University. "These lawsuits would add headaches for Chinese companies who would no longer enjoy the kind of protection they would in the past."
Foreign firms are restricted from selling games without a local partner in China, which research firm Newzoo estimates is home to more than 600 million gamers. But growth slowed for the industry after Beijing froze licenses for new games for nine months last year and attempted to reduce screen time for teenagers.
Other international companies, including U.S.-based Activision Blizzard Inc. and Seoul-based PUBG Corp., have previously sued Chinese firms for allegedly ripping off content. And the gaming industry in other parts of the world, including South Korea, has in the past been blamed for allowing other varieties of copycats.
But Byun Ung-jae, a lawyer with Seoul-based Yulchon, said China's courts have become quicker to prohibit possible knockoffs from selling.
"WeMade stands out because they've been brave and dogged enough to take the fight to the court for quite some time," said Byun, who doesn't have business ties with the company. "China's gaming industry has also grown huge now, so the country also feels it's time to provide protection for its own sake."
WeMade struck gold about 20 years ago when it released Mir through Shanda Games in China, getting as many as 200 million people to sign up at one point.
But in the summer of 2015, as Chang traveled to China, he was shocked to learn that games almost identical to Mir were in service there.
Yet his company had spotted red flags years before. In 2003, WeMade sued Shanda for allegedly copying Mir in its own game without licensing. The dispute was settled several years later, after Shanda bought a majority stake in a Korean company that is a Mir co-licensor.
Shanda, which still runs the original Mir game in China and didn't respond to a request for comment, is in a separate lawsuit with WeMade about renewing their licensing agreement.
Winning isn't easy. In April, a Hangzhou court issued an injunction, temporarily stopping another Kingnet unit from publishing one version of a game WeMade said was based on Mir. Kingnet produced a new version, sparking another round of legal battles over what WeMade says is really the same game.
It's easy to see why Chang likes Trump's toughness on China, but he also worries about a trade war escalation.
"It has been positive so far, with China showing off its judicial system," Chang said. "But if this really turns into a war, it may no longer feel like doing so."
