Bases Loaded II: Second Season was originally released for the Nintendo Entertainment System in 1989 and was revolutionary in its introduction of Player Performance Ratings, that were designed to simulate the hot streaks and slumps that every player went through during a baseball season. Batters and pitchers were each rated in three categories: Physical, Sensitivity and Intellectual, and these ratings would rise and fall as the season wore on. The Player Performance Ratings added an extra layer of strategy to the game as managers would have to determine if one of their hitters was in enough of a slump to warrant a few games on the bench. Super Bases Loaded II was Jaleco’s second baseball title for the Super Nintendo and featured a battery backup for saving statistics for all the 14 teams in two fictional leagues featured in the game, as well as the four “edit” teams. The game was the first baseball title for the SNES to add a DSP-1 chip to provide 3D like camera effects (Mode 7). Jaleco Sports: Bases Loaded II features five games total including both Bases Loaded II: Second Season (United States / Nintendo Entertainment System, 1989) and Moero!! Pro Yakyuu ’88 Kettei Ban (Japan / Famicom, 1988), as well as three Super Nintendo / Super Famicom titles: Super Bases Loaded II (United States / Super Nintendo Entertainment System, 1994), Super 3D Baseball (Japan / Super Famicom, 1992) and Hanguk Pro Yagu (Korea / Super Comboy, 1994).
