There have been some sudden moments where maybe one planet was too easy or one was too hard and [Joel] had to get up in the middle of the night.
I laughed out loud that they woke this poor dude up in the middle of the night. Like how did that conversation go? "Joel! EMERGENCY! POPLI IX is too hard! Wake up and fix it!"
Jokes aside, I think it's awesome they have a game director who can influence the story in real-time to keep things interesting.
