A few days ago, I wrote that The Last Guardian was going to be at TGS 2015, but in more abstract way than usual. I speculated that we may instead see some kind of installation, rather than a trailer. Well, I was absolutely correct as this has come to pass.
In this video shared by IGN, you can see how the BirdDog Trico was part of an interactive showcase, which had him follow people and play with the curiously as they walked by. It's lovely. I like it a lot.
Take a look here.
