Your point would make sense if you do not play video games. Because what you call a muscle memory of pressing buttons is actually a lot more. Think of the animations of the characters, their various skills, the suspense of bosses or crowds, the set design, the flow of combat. These are all important and actually do impact it, and are the game's "internal truth". The game itself is the source material, the story is a part of it. The mechanics are vehicles through which the story reveals itself, so brushing past it is not honest to the games themselves.
As for your cherry picking of games, I agree those are probably the easiest to adapt or try to get the closest to it precisely because they're the ones closest to the medium you want to translate it to. We're saying very similar things. In fact, I would argue you're agreeing with me. For you're saying that adaptations won't be the same, they won't be identical and cannot adapt every part of the game because it is impossible. But it (ideally) can get the broad strokes, expand certain things or reinterpret, while keeping passion and care for the characters/world/story. Because as you said, it isn't identical but the heart beats the same.
