Pro Baseball '88 Decision Version), is a video game for the Nintendo Entertainment System released in 1988.

The game was novelized by Peter Lerangis, as part of the Worlds of Power series published by Scholastic Books.

In the "pennant race", a player must first achieve at least a 75-55 record during the regular season, then win a best-of-7 "World Series" against L.A. or N.Y. depending whether you have chosen a team from the Eastern or Western league respectively.

In Bases Loaded, the view was from behind home plate, whereas in Bases Loaded II the view was either from the first-base line if the home team was at bat, or from the third-base line if the visiting team was at bat.

One big improvement over the original Bases Loaded included the ability to modify the starting lineup and batting order for the user controlled team, and clearly defined pitcher's roles which were outlined clearly in the detailed rosters included with the instructional manual.
