Asteroids was innovative in many ways. Space Invaders was the first
game to keep track of the highest score attained on a machine.
Asteroids took this concept further by allowing players to enter their
initials for setting one of the top ten High Scores.
Finally, although it was not the first game to do so, Asteroids
uses a vector graphics monitor to produce sharp, black-and-white linear
graphics. The vector graphics fit the futuristic outer space theme very
well.
Asteroids rocketed to dominance at the arcades, even managing to unseat
Space Invaders as the then-current top moneymaker. According to the
KLOV, Asteroids was so successful that arcade operators had to install
larger coin boxes to hold all the quarters that players plunked into
the machines...GameSpy
