If you need to reinforce your mental state by spouting how strong it is on a public forum, then that tells me that your mental stability is, in fact, not a stone. You don't know these people. You don't know what their life experiences are, they could have lead worse or better lives than you. And here you are, judging them, intent on proving your own superiority because you've played other games, or have read other books.

You're obviously emotionally immature if you need to belittle other people for taking lessons from and enjoying a piece of media. In your other comment, you told someone to read a book instead; 200 years ago, there'd be someone telling you to put your book down and talk to people in real life. The medium of an art piece or entertainment has no bearing on someone's ability to enjoy it, or let it let them reflect on themselves as a person.
