The following cards are collectively referred to as "good" Environment cards:

Bad Environment Cards

Note that the remaining Environment card, Binary System, can be either good or bad depending on how and when the card is played.

Originally, Binary System had been thought of as a good Environment card. However, one night during playtesting Ellen Endress joined my two best planets together at the beginning of the last turn. This presented a single target so tempting (P8 I think) that my binary system went Super Nova shortly thereafter. Sigh..... since then, Binary System has usually been used against other players.
