Marble Madness is an arcade video game designed by Mark Cerny, and published by Atari Games in 1984. It is a platform game in which the player must guide an onscreen marble through six courses, populated with obstacles and enemies, within a time limit. The player controls the marble by using a trackball. Marble Madness is known for using innovative game technologies. It was Atari's first to use the Atari System 1 hardware and to be programmed in the C programming language. The game was also one of the first to use true stereo sound; previous games used either monaural sound or simulated stereo. In designing the game, Cerny drew inspiration from miniature golf, racing games, and artwork by M. C. Escher. He aimed to create a game that offered a distinct experience with a unique control system. Cerny applied a minimalist approach in designing the appearance of the game's courses and enemies. Throughout development, he was frequently impeded by limitations in technology and had to forgo several design ideas. Upon its release, Marble Madness was commercially successful, becoming a profitable arcade game. Praise among critics focused on the game's difficulty, unique visual design, and stereo soundtrack. The game was ported to numerous platforms and inspired the development of other games. A sequel was developed and planned for release in 1991, but canceled when location testing showed the game could not succeed in competition with other titles.

This article is about the 1994 video game "Mario Andretti Racing" and the 1996 video game "Andretti Racing". For the current racing team, see Andretti Autosport. Mario Andretti Racing is a video game that was released in 1994 on the Sega Genesis/Mega Drive. It was an early title in the newly created EA Sports line, and was developed by Stormfront Studios. The game was produced by famed sports game developer Scott Orr as part of his collaboration with Richard Hilleman in the creation of EA Sports. Race driver Mario Andretti personally guided the development of the AI used by the non-player drivers in stock cars, Indy style open wheel racing, and dirt track racing. The game's greatest innovation was the presence of different physics and AI for three kinds of racing in one cartridge. The success of Mario Andretti Racing led Orr and Hilleman to work with Stormfront to launch the highly successful NASCAR Racing series, which continues as one of the best-selling franchises in the EA Sports lineup today. A second game, called Andretti Racing, was released for the Sega Saturn, PlayStation in 1996, and for PC in 1997.
