Why wouldn't the stack people just rush the guy anyways? He has one gun? Felt odd to just let him walk up, then he opens the door, doesn't shoot and.. ?? That part didn't work for me.

I actually had no problem with the pop culture being centered around 80-90s era. One, it's the product of the creator's influence, and two, if everyone is spending all the time in these VR worlds then there isn't anyone creating pop culture outside of it in order to influence the world within. It also wasn't everyone doing so, but mostly the egg hunting players.
