I watched Pewdie's part 1 of his playthrough, and most of it consists of the same stuff we saw from the demo (Meaning the demo consists of footage from early game mostly), nothing too impressing in there.
Although it could get better later in the same way AMFP might (Many people said the startying of AMFP is one big tease which gets better, and better), and Cry said in his video description that while it was predictable at times it was still very enjoyable.
