It would seem that Playerunknown's Battlegrounds developer PUBG Corp has either overestimated the number of people playing the battle royale title or misjudged their enthusiasm for collecting in-game items.

That's going off claims made by dataminer PlayerIGN - as reported by PCGamesN - who took to Twitter (below) to show that the company has reduced the number of in-game items that players need to collect to unlock in-game lore and a helmet item.

The collectable DVDs were introduced earlier in the month, with players having to collect a total of 1.95m of these discs in order to unlock the aforementioned goodies. This milestone has been brought down to 1.3m. 

As for why PUBG Corp has had to make these changes, it's possible that the playerbase for Playerunknown's Battlegrounds has dipped to a point where this kind of large scale meta-game simply couldn't work at the scale it hoped. The title's concurrent user figure has dropped by 82 per cent from its all-time high in January 2018, though that was an admittedly ridiculous high.  

It's also possible that many users simply didn't know what the new boxes with DVDs in even meant, given that there was nothing in the game itself to actually explain their presence. 

PUBG Corp also recently changed the way that loot boxes work in the battle royale title, with users no longer required to buy a key to unlock them.
