I feel like there is a lack of explanation for the quest system accessories. I just kept thinking, "What are they writing about?" I wish there had been an explanation while looking back in the middle, but it was almost at the end of the section, "Does it work well?" It felt like the instructor was just copying and pasting something that was already completed. In conclusion, I understand how to use SO, but when it comes to the quest part... I don't know. I've taken paid Unity lectures online from various places, but I don't think they were the ones that really resonated with me.
