Arch Rivals

Arch Rivals is a basketball arcade game released by Midway in 1989. Billed by Midway as "A Basket Brawl", the game features two-on-two full court basketball games in which players are encouraged to punch opposing players and steal the ball from them.

Arch Rivals allows players to select from a variety of fictional teams (although arcade operators can change the team names to reflect real ones) and players. One playable character, "Tyrone" was also featured in the animated Power Team segments of the television series Video Power. Home versions of the game were released for the Nintendo Entertainment System, the Sega Genesis/Mega Drive as well as the Game Gear. Emulated versions of the game were included in the compilations Midway Arcade Treasures 2, Midway Arcade Treasures Deluxe Edition, and Midway Arcade Origins.

The game has been considered a forerunner to Midway's popular arcade basketball game, NBA Jam.

Gameplay

Games generally follows standard basketball rules; a full game consists of four quarters, with four minutes each. Each team has two players, and the objective of the game is to outscore the opponent until the final buzzer sounds. A player can call for his teammate to pass him the ball or to shoot it in this battle royale.

Arch

An arch is a curved structure that spans a space and may or may not support weight above it. Arch may be synonymous with vault, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the Ancient Romans who were the first to apply the technique to a wide range of structures.

Basic concepts

An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses and, in turn eliminating tensile stresses. This is sometimes referred to as arch action. As the forces in the arch are carried to the ground, the arch will push outward at the base, called thrust. As the rise, or height of the arch decreases, the outward thrust increases. In order to maintain arch action and prevent the arch from collapsing, the thrust needs to be restrained, either with internal ties or external bracing, such as abutments.
