I need some suggestions on what to play. Single Player games only. Most of the games make me feel lonely and alone. In most of the games, the protagonist has to deal with the problems on their own, like Control, Crysis, Ghost of Tsushima, God of War (I liked the original 6 more than the new ones, even though the new ones had companions), horror games like Outlast, Echo and Alan Wake, and many others.
I want something that won't give me anxiety. I really enjoyed Guardians of the Galaxy, having those teammates by my side always made me feel "safe". I also liked Spider-Man and Deadpool because the humour makes me feel comfortable. In old Harry Potter games, Ron, Hermione and Harry were usually together, so, I never felt alone while playing those either. In Indika, that one hand man was with me for most of the game.
Open world games also give me less anxiety, like most Assassin's Creed games, Ghost of Tsushima, Just Cause series, etc.
I think you all get my point. So, what do you suggest I should play?
Which typically culminates in rolling up everyone on Earth by the time you get to the final stage, no less. If that's not a group hug, I don't know what is.
Edit: I'm also going to second the Psychonauts recommendation, especially the second game. Despite the gameplay itself inevitably lending itself to the protagonist performing every little bit of work by himself, there are strong themes of teamwork all throughout the game's story and the excellence of its final sequence cannot be understated:
Ding dong.
Whale-O-Gram.
I wanna wad you up into my life / Let's roll up to be a single star in the sky
Such a killer fucking happy/upbeat soundtrack, too.
To your edit, similarly the final sequence of Nier Automata is so deeply rooted in not being alone, and encouraging one another, and being there for one another. A chance to break the cycle.
If I recall correctly, Yoko Taro had said he had been somewhat inspire by this Coca-cola campaign the "Small World Machines."
