I would counterargue a bit by saying that games like FireWatch/Gone Home that are played in a first person view are inherently more subversive than a typical 3rd person game, making it more likely that an interested player will buy the game.
I personally have a much harder time finding watching streams of 1st person perspective games compared to 3rd person.
LiS was infinitely more complex than any game Telltale game that I can recall.
