Terra Mystica: Merchants of the Seas

Worth it

Our take: BGG rates it 8.1 from about 1,200 ratings with weight 4.17 (heavier than the base 3.97). In a BGG thread asking if it is a must-have, one poster calls it 'a great expansion' but warns it 'makes the game significantly more complex' and that it only slightly improves the 2-player game; another poster says it is 'not must have'; the co-designer James Ataei says it improves 2-player by adding tactical ship movement and interaction. On Reddit, commenters say Merchants is 'a fabulous expansion which increases the decision space' and 'fundamentally changes the way the game is played', while Fire & Ice 'just adds a bit of variety'; others put Fire & Ice first. It is the pick for groups that want a deeper, more interactive game rather than just more factions.
What you need first: Just the base game

What it adds: Ships and a new Shipyard building with twenty faction-board extensions, trading ships that give VP and resources (and power to the receiver), ships that can dig and build dwellings, 12 new round-scoring tiles, four ship-related Favor tiles, three new bonus tiles, three additional power actions, two new town tiles and two new maps (Lakes and Fjords).
What it fixes: Adds an extra tactical movement layer and more interaction; the designer says it improves the 2-player game because ship trading forces interaction. It also carries the official updated starting-VP balance list.
