R.B.I. Baseball 21 is no longer available for purchase on the PlayStation Store. It was removed from digital storefronts in August 2021, due to a dispute between the game’s publisher, MLB Advanced Media, and Major League Baseball. As a result, R.B.I. Baseball 21 is not available to play on PlayStation 5.
The only way to play baseball on PlayStation 5 is with MLB The Show 23, which is published by Sony Interactive Entertainment. MLB The Show 23 is a more realistic and immersive baseball game than R.B.I. Baseball 21, and it features all 30 MLB teams and players. It also has cross-platform play, so you can play against your friends who have the game on other platforms.
If you’re looking for a baseball game to play on PlayStation 5, MLB The Show 23 is the best option. It’s a more polished and complete game than R.B.I. Baseball 21, and it has the official licensing from Major League Baseball.
