Korean Game Rating Board has posted ratings for PUBG on PlayStation 4 and inadvertently leaked the game's port to Sony's platform. This theory is compounded by the fact that PUBG is reaching the end of exclusivity contract with Microsoft.
While the website is in Korean, it is possible to use either Google Translate or browser plugins to see what the content is all about. The translation is not 100 per cent accurate, but it's precise enough to show the context of the post .
PUBG is classified as an FPS shooter on the site and there is no mention of it being a third person shooter so there is a hint it will be somewhat different than PC and Xbox One versions once the game arrives to PlayStation 4.
Due to intense violence, realistic blood colour and realistic weapons, the board has classified PUBG as a "Not for Youth" type of game, although it's unlikely all youth are subject to that ruling.
After all, H1Z1 is fairly similar and the game has enjoyed quite the success on PlayStation 4 worldwide in the absence of PUBG. Technically, Fortnite is also a battle royale but there seems to be a large population of players who prefer realistic graphics over cartoonish ones and shooting over building.
Microsoft scored big when they snatched themselves a PUBG exclusive deal due to the game's lightning fast rise to the top of the gaming world. Now the game has somewhat fallen from grace and is losing players rapidly, as PUBG Corp are managing to retain only about 33 per cent of the player base they had in PUBG's prime. Therefore it's safe to say Microsoft enjoyed the best of PUBG exclusively and Sony are getting the scraps.
Meanwhile, Call of Duty: Black Ops 4 might overtake both battle royales with its Blackout mode since it has been very well received during the beta and it's coming less than a month from the time of writing, on 12 October 2018.
