During baseball matches the player gets to control batters and pitchers.
Batting and pitching both use tiered difficulty systems: batting ranges from simple timing swings to advanced control of swing power and strike-zone placement, while pitching uses a “golf swing” style meter where precision and control matter.
The game also includes simple team management gameplay, with the ability to buy and sell players.
Other highlights amongst Grand Slam 's feature set include: A trade AI engine that would examine the needs of a team and decide if a proposed trade was in its best interest.
Catcher AI and pitch signals, helping a player learn how to pitch to each batter's strengths and weaknesses.
Attention to details and baseball flavor, such as players that would blow bubble gum bubbles during an at bat, light- hearted commentary, an All Star Break during season play (complete with a working voting ballot), and an in-game JumboTron scoreboard that would show animations after home runs.
Grand Slam was one of the early adopters of 3D accelerator card technology and also offered full 3D play in software alone.
The Playstation and Saturn versions were 3D by default.
About PlayStation
The original PlayStation (1994) brought CD-based gaming and 3D graphics to the mainstream, ending Nintendo's console dominance of the previous two generations. It's now firmly in "retro collecting" territory: original jewel cases with intact manuals command a real premium over disc-only copies, and several RPGs from its later years (when Sony deliberately courted the genre) are among the most expensive commonly-collected games from the era.
Gamevaro tracks Grand Slam for PlayStation with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Grand Slam to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PS1 release dates back to 1997.

Market insights
Rarity & condition

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
