I picked this up in 2020. I was bored, wanted to try something new, and felt that the time was finally right to branch out from d20 systems.
This set features three books: an abbreviated rulebook to teach the game, a book that features a solo campaign, and a book that features traditional modules to help teach other players Call of Cthulhu 7E. It also features handouts and, like every starter set I've encountered thus far, a set of dice.
This is one of the best starter sets I've ever encountered. The rules are pretty complex even by RPG standards but these books do a great job teaching them. I'm torn on the solo campaign, though. Enough checks are featured that you get a decent grasp on the system but the choose-your-own-adventure style of the narrative doesn't really fit how CoC is played, so it feels a little disingenuous as an ambassador of the game. I also found the dice set to be pretty bland. The real stars of this box are the other modules and the handouts. The system didn't click for me until I read those modules. It's a bit less flexible than 5E but the elegance with which it intertwines with the story is incredible as it requires a lot less having to figure out situational modifiers which really keeps the game moving. CoC has always relied heavily on handouts as it focuses on solving mysteries. It really makes you feel like an investigator compiling information for a case and I love it.
