If it helps you decide, the Night Springs DLC is technically a prequel to AW2 but more or less standalone. The DLC is also pretty short with 3 separate chapters that are just a couple hours long total, and locations are reused from the base game. I believe there were supposed to be a couple extra chapters that got scrapped (partially due to James McCaffrey’s passing). That being said, I did enjoy it and think the third episode in particular was pretty interesting.
