I don't... understand the complaint here. These games don't gain anything from forming any addiction cycle unless they have predatory practices like lootboxes or any form of microtransactions to squeeze more money out of addicted players, but... these don't. At lease PWS doesn't.
The fact that these games are designed to give people an objective to work towards isn't inherently a bad thing or predatory either. It's just an aspect of video games, and one that many people enjoy. If they're designed to give people things to work towards, that gives people a reason to want to continue to play the game if they enjoy it. This isn't predatory. In order to experience the gameplay cycle and find that you enjoy it, you have to already have paid for the one-time purchase, and no more money can be taken from you.
And the alternative is to have an experience that doesn't have any inherent gameplay loop? Sure, that's fine, I'm sure some people would enjoy that. But not me, and not a lot of other people. It's not inherently better to not have a built in gameplay loop, just a matter of preference. It doesn't make a game soulless to have this, or money hungry. Just a design principle that a lot of people enjoy.
I would understand all of this in regards to actually predatory games - ones that draw people in with really shallow gameplay loops and then push microtransactions. But these are games that a lot of people find fun because of their gameplay experiences, and they don't do anything predatory. They're just simple experiences that aren't meant to be big challenges, or miserable, or unpleasant. Just simple things to do that you might enjoy.
Also, the idea that misery is an inherent part of hobbies, and that they only exist as the thing that you happen to be doing, is very confusing to me. I don't find any of my hobbies to be miserable at any point in time. They aren't always perfect and idyllic, there are times when they're less fun, but if they were ever miserable, I would not be doing them. They wouldn't be hobbies for me.
