Istanbul: Letters & Seals

Worth it

Our take
BGG rates it 7.73 from 1,633 ratings. Buy it second: a BGG poster says to get Mocha & Baksheesh first, and several owners call both expansions fun spice rather than necessary.
What you need first
Just the base game
What it adds
Mail delivery to shopkeepers for money, secret-society information sold for rubies, and a slower companion who needs no assistants.
