Its the age old subjective vs objective criteria, and for certain people of different perspectives one will outweigh the other. Nostalgia is very subjective - most of those classics are called classics because they were fantastic at the time of release. They dont hold up today on a technical level, so objectively their quality by today’s standards is dirt, but whether or not someone still finds it entertaining or fun to play is entirely dependent on that person. The only way to measure that is to take an average of the judgemental reactions of many people - essentially consensus.

The problem with phone games is that objectively the large majority of them are poorly made, with subversive mechanics meant to manipulate the casual audience into spending on them. Their goal isn’t fun so much as addiction. It works because it is so largely available to a massive casual audience. The large majority of these people wouldnt bother to purchase a console or a PC for gaming. I’ve met people who actively say they think video games are a waste of time but they’re on level 1000 of candy crush and spending money on power ups. These people do not visit gaming forums and are not gaming enthusiasts, they dont see an issue, nor would they care if you point it out. Subjectively, they like it, they’re having fun, and that’s fine, but that is not the audience you are speaking to here. For this crowd the issues are readily apparent. Its immediately obvious to use why these games are balanced poorly, why ads are shoved in our faces constantly, why the constant updates are anti-consumer. An enthusiast audience will always be more critical of such practices that the larger casual crowd easily ignores.

Last time I went to mcdonalds it was because of that same kid who loves phone games. He was so excited for chicken nuggets. I tried one, it was horrible. I choked down a burger that is an insult to burgers. No food enthusiast would ever recommend this, no self respecting chef would ever endorse this, and I can easily make better food at home for cheaper. But they’ve served millions, and have franchises world wide! People love it, so it must be great! It sure as fuck is not, and I certainly have the capacity to be a more discerning consumer with that just like I am with video games or any other interest.
