What type of game would i design in the 80's?

In my game design class today, I was asked to answer the question: if I were to develop a game in the 80's, what type of game would it be?

 Given the limitations of the 1980's e.g character control limitations and graphical limitations, if I were to develop a game it would be played in a top down or side on perspective and graphically it might be more cartoonish due to violence being more socially unacceptable at the time. Given that a lot of games were played in the arcade it would need to suit being simple and addictive so that the players keep paying to play more.
