Terraforming Mars

Play a card (Requirements)


In order to play a card you must meet its requirements and be able to perform the effects stated on the card, with the following exceptions: You may play a card that...

- Raises global parameters that have already reached their goal (for example: when there are no more ocean tiles, or when the temperature is at +8 °C).

- Adds resources that you can’t collect (for example: adding microbe resources without having any microbe project to place them on).

-Removes resources for any player (red-bordered resource icons, see example on card C below) if you can’t or do not wish to. Even if these effects can’t be performed, you may still play the card, performing all other effects as usual.
