The King in Yellow - my group ran the first part, and we loved 1895 Paris but our GM found the cards difficult to manage, and as players we found the modified GUMSHOE mechanics meant you very quickly ran out of points and just started failing at everything, cueing the GM to hand you more cards. Some cards are hard to get rid of, and 3 physical cards = death, 3 psychological cards = permanent insanity.
We had a break after suicidally attempting to stop Cassilda and her sister. We come back after a few months and play part 2. The modified world war is interesting, but less enjoyable then Paris.
We aimed to come back and do part 3, but coronavirus got in the way. Also, the tensions of online roleplaying meant one of our group quit and decided to play in someone else’s Runequest game rather than keep clashing with the rest of us so much.
