Obsession
Which Upstairs, Downstairs tiles and guest cards can I add to a base game that does not use the new servants?
Add the guest cards (the designer says they rebalance the prestige mix and can stay in permanently), the Carriage House and the prestige rating 5 tiles. Leave out the Renovated Kitchen and Housekeeper's Room, which need the new servants, skip milestones and the extra promo content, and use the base objective deck. Tiles with a small U under the sorting number are unique to the expansion; the first-edition replacement Barn and Servants' Hall are not needed for 2E owners.
