R.B.I. Baseball is a baseball sports video game series. R.B.I. stands for "runs batted in". Launched in 1987 as a localized version of Namco's Family Stadium series, the R.B.I. Baseball series initially ran through 1995. In 2014, the series was rebooted as a competitor to MLB: The Show, with releases each year until its cancellation. The series ended in 2022 with the release of MLB The Show 22 on the Nintendo Switch.

The Nintendo VS. System is an arcade system that was developed and produced by Nintendo. It is based on most of the same hardware as the Family Computer (Famicom), later released as the Nintendo Entertainment System (NES). As Nintendo was planning to release the NES in North America, they were aware of the video game crash of 1983 and its effects on the home console market. However by March 1984 the arcade industry recovered enough for a plan to introduce NES titles there, with the VS. System later being a presentation to players who did not yet own the console. It became the first version of the Famicom hardware to debut in North America.
