No, PC culture isn't ruining gaming. Just...not even close.
The real culprits are lootboxes, timesavers, roadmaps, anthologies of DLC, basic features held ransom behind paywalls.
"PC culture", be it real or imagined by yourself, isn't responsible for the likes of Battlefront 2, Fallout 76 or Metal Gear Survive.
(it's the 'triple A' standard-stock business model)
