Sort of agree but it also depends on what you mean by grind. A game like war thunder or enlisted you could call it a grind to unlock top tier things, or throw money at it. Or you can just play the game for fun while spending little to nothing.

Seriously, I have had conversations with other players before and even if I wanted to spend £100 on either game there is nothing really worth me spending it on. Even subscribing to the game just isn't worth it as the main benefit is more xp. But that is more xp to unlock things I don't care for. The other benefits are so small it isn't worth bothering with.
