Terraforming Mars · Board game rules
Which expansions are required for Terraforming Mars?
Quick answer
No expansions are required to play Terraforming Mars; the base game is complete.
Details
The rulebook excerpts provided do not mention any mandatory expansions for Terraforming Mars. The base game includes all components needed for standard play.
The Corporate Era (an extended game variant) and Draft variant are optional rules described in the excerpts (page 13). These variants use cards and mechanics already included in the base game:
- Corporate Era adds cards marked with a red and white icon, which are part of the base game but excluded in standard setup.
- Draft variant modifies the Research phase and is not required for basic gameplay.
Expansions like Colonies, Prelude, or Turmoil are not referenced in the provided excerpts and are separate purchases. They are optional and not required to play the base game.
Watch out: The rulebook distinguishes between the standard game and optional variants. If you own only the base game, you can play without any expansions. Expansions add new content but are not necessary for core gameplay.
