It remains for the player to decide how much fuel to take on, what thrust to use, whether to try to blast off slowly, or whether to launch at somewhat higher velocity. Although the player of this game has the help of a computer, it will only tell him the statistics of the journey. Part of the reason is that the game is unbelievably difficult because all the physical laws and relationships are obeyed. Believe us when we state that it really is a thrill. If you succeed in making a landing on another planet then your reward is the thrill of having been able to do so. There are no prizes, no free goes, nothing else. The purpose of the game is to blast off from the planet of your choice and travel throughout the solar system.

Hence every game is different and presents different problems to the player. Each time the game is played the planets the planets and stars in the solar system are differently placed, but still in correct relationship to each other and to the Sun.

All the orbits of the various planets are correctly calculated, as are their orbital speeds and gravitational pulls. The software programs your TRS-80 or SYSTEM 80 to produce a complete and highly accurate simulation of the solar system. To label this program as a game is to underplay the incredible realism of what can be described as a simulation.
