Tbh, PUBG has been reporting considerable user decline in recent times. The main issue is that the game hasn't exactly evolved in what already seems to be a saturating market. Maybe PUBG2.0 could solve this but would it actually solve the weird in-game monetization strategy? not sure if the existing strategy is exactly what an average user needs.
