Gridiron Fight,[lower-alpha 1] also known as All American Football,[3][4] is an American football video game developed and released by Tehkan (later known as Tecmo) for arcades in 1985. It is a one or two player game based on gridiron football (American football), and was released in a cocktail cabinet form factor. The game uses trackball controls, used to determine the speed and direction at which the player runs.

Designed by Shin-ichiro Tomie and programmed by Michihito Ishizuka, with background graphics by his wife Rie Ishizuka (Rie Yatomi), the same team went on to develop the association football game (soccer game) Tehkan World Cup later the same year. It was also a precursor to the American football game Tecmo Cup (1988).

Gameplay

Tehkan Gridiron Fight is a two-dimensional top-down scrolling American football game in which the player(s) control the virtual player on their team who is closest to the ball, with the trackball determining the speed and direction at which the player runs. A single push-button labeled "Kick" causes the virtual player in possession to release the ball with the same force and direction in which he is currently running. (This button is duplicated on either side of the trackball for left or right-handed players.) The Player 1 (red trackball) side contained two additional push-buttons for choosing between Single or Two-Player games. Before each play, players are invited to select from a variety of formations, e.g. "Sweep" or "Draw". The formation selected is displayed on a seven-segment LED on the player's control panel.

Although the graphics are two-dimensional, the height of the ball can be determined by its growing larger while its shadow appears on the ground. Also on the side of the screen is the score and a clock which counts down to zero, the point where the current game ends.

Hardware

Two slightly different cabinet shapes were released - one with straighter edges and vertices in profile and one with more rounded edges akin to its stablemate, Tehkan World Cup.

Processors and sound — Tehkan Gridiron Fight used two Z80C 8-bit CPUs at 4.608 MHz for processing. For sound, it employed one Z80C at 4.6 MHz, two AY-3-8910s at 1.536 MHz and one M5205 at 384 kHz for FM and samples. Although this produced three-channel music plus sound effects, all sound was fed through a mono amplifier in the cabinet housing. As machines aged the amplifier was known to fail, resulting in silent gameplay.

Screen and resolution — The screen was a horizontally mounted 20" color raster CRT monitor fed at 256 x 224 pixels by 768 colors by 60 Hertz.

Trackballs — The game unit consists of two 3" optical trackballs. These are made of semi-transparent plastic, and illuminated from below such that they shine blue or red, depending on the color of the ball.

Development

Gridiron Fight was developed by Tehkan. The game was designed by Shinichiro Tomie,[5][6] and programmed by Michihito Ishizuka, who was also responsible for sound design, having previously programmed the sound driver for Bomb Jack (1984).[7] His wife Rie Ishizuka (also known as Rie Yatomi) was responsible for the background graphics, along with other female staff members. Michihito and Rie Ishizuka had previously worked together on Senjyo (1983) and Bomb Jack.[7]

Reception

In Japan, Game Machine listed Gridiron Fight on their April 15, 1987 issue as being the second most-successful table arcade unit of the month.[9]

Jay Carter of Cash Box magazine compared the game favorably to the classic Atari Football (1978), stating that Gridiron Fight updates its essential elements. He said it has "everything from full color screen action to glowing track-balls and a full selection of both offensive and defensive plays that should stir up some strong head-to-head competition when the school semester ends and the kids are looking for some rainy day challenges and excitement."[8]

Legacy

Tehkan World Cup

Tehkan World Cup (1985) was an association football video game (soccer game) released later the same year, featuring almost identical hardware. It employed the same twin trackballs with an action button duplicated on either side and a similar cocktail cabinet design with horizontal screen. The primary hardware difference was the absence of the seven segment LED adjacent to the action buttons. The software of the two games exhibited a similar top-down two-dimensional window-on-the-field graphical design.

Both games were developed by several of the same team members. Both were designed by Shinichiro Tomie, who was a big association football (soccer) fan. After designing Gridiron Fight, he immediately wanted to adapt the gameplay format of Gridiron Fight for a soccer game.[6][5] Michihito Ishizuka reprised his role as the programmer, while his wife Rie Ishizuka worked on the character design and background graphics.[7][5] The team felt the trackball controls of Gridiron Fight was complex, so they decided to simplify the controls, making it so that the player can run with the trackball and press one button to kick. This led to Tehkan World Cup becoming a major arcade hit.[6]
