Lunar Lander has the distinction of being Atari's first vector graphics arcade game, a simulation based on lunar landing games that had become popular in the nascent computer gaming scene. The concept is simple: pilot a ship (similar visually to the US lunar module) to the moon's surface, managing attitude, velocity and fuel to land on designated areas. Both the game's simple but precise graphics and its spaceship-like control scheme give it the feel of a hardcore physics simulation, and it's tougher than it might look. The look and concept paved the way for numerous Atari vector games to come, most notably the similarly-themed Gravitar.
