| Enemy | Anybody that isn't allied with you. |
| Gravity | Everything that can't be changed about a star system. Any planet between 0.4 G and 2.5 G can be made profitable, if enough people are on it and it is fully terraformed. An ideal planet is 1.0 G. Each player has a different idea of what 1.0 G is. |
