@Chris-Goodman Games The Peru chapter for Masks is only in the latest incarnation. Originally, I think it was a weird optional start in Arkham, but the action and clues to kick the campaign off were all in NYC. I don't know how many iterations there are. Maybe 3? 4? Definitely less than 7 I do like the new Peru chapter! I also think it's supposed to be some sort of weird flashback. Might be fun to try it in media res where you skip to the end of the chapter for just the combat, but the windup is also pretty nice Call of Cthulhu does not use standard XP; skill improvement is based on successful use and a roll-over-your-skill mechanic, which can feel limiting. However, in Masks of Nyarlathotep, the frequent travel downtime makes this system shine, as you get regular chances to improve your skills between chapters. There is always a long sea journey around the corner, allowing investigators to make improvement rolls for skills they used in the previous chapter. This is a rare opportunity in Call of Cthulhu, as most campaigns don’t offer such generous downtime, so players can actually see their characters grow and adapt as they travel the globe in pursuit of clues
