It's the same thing that is missing from Avengers. It's soo frustrating. I have SM, IM and AV all sitting in a row in my gameroom. You play SM and get immersed in the game with the sounds, music, call outs and Doc Oc multiball. Then you move over to IM, with sound bytes from the movie, music, and Jerricho multiball - again, an immersive experience. Then onto Avengers and you're like "Captain America!" - what the hell? You hear some call outs from Thor but can't place them, and then Hulk has a few good moments. You leave the game like - was that from the movie? Ok.
I'm sorry, Stern has gotten cheap. They don't want to pay for sounds clips from the studios for some reason. So much content in GOT like AV, and I'm just not convinced they plan to create the immersive experience because they are finding the cheap way out. I feel like I'm buying an Avenger pinball machine that's a knock off from China. It looks good but the guts are all wrong. That's how call outs are being treated. Sad, really.
