That said, the video is missing any kind of video game clips and I wonder if this has to do with YouTube's new policy in regard to Let's Plays and reviews? I hope not as this episode, while good, lacks the fast pacing the entire first season had.

I'm an Engineer and built the video game community Cheerful Ghost and text based mini-MMO Tale of the White Wyvern.
What is YouTube's new policy in regards to LPs and reviews?
It's a big sort of sweeping thing that many people have commented on. I'd recommend a few searches on it as I don't want to get into the specifics entirely.
But in short, they are taking away ad revenue for let's plays and people that use game footage for the big publishers.
Dang
