Mysterium: Secrets & Lies

Buy this first

Our take
BGG rates it 7.82 from 2,155 ratings (base game 7.19). It carries the same extra card count as Hidden Signs plus story cards, and posters say you can add the new cards first and the story cards later. Thin evidence: no direct reviews compare the two.
What you need first
Just the base game
What it adds
8 new suspects, locations and objects, 42 more vision cards and story cards ("motive for the crime") that replace object cards so the ghost must tell how the victim died.
What it fixes
BGG forum posters say the base game's only weak point is limited card variety.
