'''''R.B.I. Baseball''''' is the most famous 8-bit baseball video game globally, a cornerstone in baseball game history. Featuring simple gameplay and a light-hearted presentation style, ''R.B.I.'' made a major impact in both North America and Japan, diverging after this release into two totally separate series: The Tengen-developed ''R.B.I. Baseball'' series that would continue on NES and then Sega Genesis, and the Namco-developed ''Famista'' series, ongoing now for over three decades.
