Fortnite's Battle Royale mode was added in September 2017, two months after the game originally launched, and since then it and PUBG have slugged it out for supremacy as top Battle Royale game - both games have now passed the 40 million-user mark.
Going forward, PUBG Corp. outlined three top priorities: performance, server-side optimisation, and cheating. As Fortnite was indeed released in the region, the injunction was unsuccessful-that said, PUBG remains significantly more popular in Korea than Fortnite.
However, analysts suggest the popularity of PUBG has waned since January, while Fortnite continues to attract more players. Based on the battle royale model, the game sees up to a hundred players fight to the last standing in an ever-shrinking and otherwise unpopulated map - and it's this model, based loosely on the book, manga, and live-action film franchise Battle Royale, of which PUBG seems to be claiming ownership.
Neither Epic Games nor PUBG Corp. responded to Variety's request for comment. It's also now the most-watched game on Twitch and YouTube.
PUBG introduced its game a year ago and it became a huge hit as players embraced the Hunger Games-style concept in which 100 players race to kill each other until there's a sole survivor. The last time a licensor tried to sue Epic Games, it put Too Human developer Silicon Knights out of business when Epic countersued and won in court. At the time, the executive stated that the company would "contemplate further action" against Epic Games.
"Although we've made some meaningful improvements to PUBG, we've fallen short in other ways", the dev team wrote.
There's also no arguing that PUBG, which stands for PlayerUnknown's Battlegrounds, came first.
Interestingly, it's worth remembering that PUBG actually runs on Epic Games' Unreal Engine 4.
