Yes, such comparisons crossed my mind. In general, the more I got acquainted with the game, the more I began to notice that so many works somehow refer to The Last of Us – in a visual or thematic sense. Logan, for example.
And yes, a similar trope [с взаимоотношениями мужчины и не родного ему ребёнка] have been used many times, in many different ways. For example, in the manga “Lone Wolf and His Child”, in “Paper Moon”.
But the thematic proximity of The Mandalorian and The Last of Us did not bother me – here, perhaps, I might not repeat myself more successfully.
