Asteroids appeared in 1979. In this game, you were a single small ship trapped in an asteroid field. You had to blast the big rocks into smaller and smaller pieces, until you killed the last piece and more asteroids appeared. Occasionally, a small alien ship would show up and shoot at you, but generally it just ran into me.
I never got Asteroids. Frankly, if you were dumb enough to fly around in an asteroid field, you probably deserved to get hit by one. Remember The Empire Strikes Back? Even the Empire does not fly into asteroid fields and they have a callous disregard for human life.
And who or what was this other alien ship? It was obviously alien, as it was a small oblong saucer (and humans never pilot those). Why was this alien also in the asteroid field? Why was it attacking you? Could you not work together to escape what was inevitable death? Could not a great friendship flourish which would result in the uniting of two disparate races in harmony? Apparently not, as the little bastard insisted on attacking you. Stupid alien.
Up next: More Aliens!
