I really like Episode 1 so far. I won't finish it tonight because I went and read the whole Book of Goblins as soon as we found it. It's a nice little children's book, and it gives some good insight into the characters (most of whom I haven't actually met yet, but I'm recognising them from the book when I do see them).
Man, it's just a lovely looking game, too. I thought Life is Strange looked really nice for the time, then LiS 2 even nicer, and this is even more of an upgrade. The artists at Dontnod have a great eye for where to add detail and where to keep things softer. It's a joy to look at.
