to be fair, that's partly the fault of the games themselves too. When the game does not provide immersion or a good story, all left is minmaxing. Developers who only add "content" and not actual memorable experiences make it so players just try to grind the game as fast as possible because they don't fundamentally enjoy the game loop, they just play for the extrinsic rewards (loot, skins, completion, achievements, whatever).
even games like minecraft are minmaxing now, even though it used to be all sorts of creative things, since the game encourages minmaxing and discourages anything else. (just see how things like minecarts, redstone etc. have been utterly neglected - in favour of exploiting elytras, villagers and building farms)
