I don't get the sense that he has any real anticipation of the game and certainly, if he really wants to know more, there's much better ways to do that than the kind of deconstructive oversimplification he engages in (another pathology of this crowd). It's intentionally backhanded to call it "just a walking simulator". There's easily accessible information out there that will readily confirm you do plenty more than that, so this is clearly not even a real attempt to try to understand what the game is.Maybe he's unsure and wants to know more so that he can feel more secure in his anticipation for the game.
There is a lot of feelings about something between "I know it's my cup of tea" and "I know it's not my cup of tea", especially when you consider how much stuff there is that we don't know about this game.
And honestly, why should anyone care how "secure" he is about his anticipation of this game or the lack thereof? Anticipate or not, you really don't need to have a public hissy fit about it. There are plenty of other fish in the sea.
