Family Circuit is an F1 racing game and part of Konami's "Family" series of sports games for Nintendo systems. The player controls the vehicle from a top-down perspective, which had been getting marginalized by the then-popular behind-the-car perspective of games like OutRun.
The player is able to customize their vehicles before races, editing acceleration and speed as well as their color scheme. They then compete in time trials and races with other vehicles, though as there is no vehicle collision in the game both modes play very similarly. While collisions won't damage the player's vehicle going off-course will, and the player may need to stop at the pit lane occasionally for repairs.
The game was later adapted for the PC Engine in 1991 with the new name of World Circuit. Namco would use the "World" brand for sports games released on non-Nintendo systems, like World Stadium instead of Family Stadium. Family Circuit would also see a couple of sequels: Family Circuit '91 and Super Family Circuit.
