Terraforming Mars: Colonies vs Terraforming Mars: Venus Next

Short answer: buy Terraforming Mars: Colonies first. The usual second buy. It adds some rules, so get used to the base game first.

Pick Terraforming Mars: Venus Next first instead if this sounds more like your table: Adds cards and a fourth track but makes games longer. Skip it if your games already run long.
