Atari’s 1984 arcade hit was a very early proponent of isometric (meaning: “equal measure”) graphics, with a viewpoint that takes an overhead, three-quarter perspective of the game play area, and as a result was a huge influence on many games that followed it.

It wasn’t the FIRST isometric game ever made, but it was certainly one of the first really popular ones.

Race down the landscape, avoiding hazards as you go, and make it to the goal area before the timer runs down.

Marble Madness still stands up extremely well today, being very playable and beautifully constructed.
