Watched all 3 of the messages. I'm super excited. The common theme from ND devs appears to be that the leaks don't come close to telling the entirety of the games story or portraying the actual experience of playing through the game.
Weirdly the fallout from the leaks has me even more excited, because without knowing the details of the leaks, it sounds like the game will be taking risks and pushing boundaries. Given how safe and predictable stories and characters in most games are these days, I'm glad TLOU2 is daring to push things further (hopefully).
I just hope the game is as emotional, shocking, intense, engaging, scary, atmospheric and fun as the first game was. Mechanically and in terms of AI it certainly looks to be a huge improvement in so many ways.
