The makers of Fortnite, one of the world's most popular video games, have been accused of copying rival title PlayerUnknown's Battlegrounds (PUBG).
The battle royale genre itself is specific and new, but there's not really any new individual elements-the genre is just a successful remix of things that already existed, including last-man-standing modes, loot boxes, maps decreasing in size, etc.
However, analysts suggest the popularity of PUBG has waned since January, while Fortnite continues to attract more players. It is worth noting as well that PUBG actually runs on Epic Games' Unreal Engine 4.
Bluehole has been vocal about the similarities since the new mode was released in September. More than half of "Fortnite" watchers were tuned in to popular streamer Ninja, a former "PUBG" player who ditched it for "Fortnite" earlier this year.
The reasons for that are complex. To improve performance, it will first address the way lighting effects are processed as well as the way vehicles move across different ground surfaces, both of which are causing players' GPUs to overload. The artwork in "Fortnite" may appeal more to kids, and Epic's game is also "cross platform", meaning players on PC, Mac, game consoles and mobile devices can play against each other.
It seems like the claim is specifically going against Epic Games in Korea, which could hamper the company's plans to launch Fortnite in the country later this year. 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.
This is a developing story.
