Steve Garvey vs. Jose Canseco in Grand Slam Baseball finds some very ingenious ways to solve the problems that plagued baseball video games of the time. For example, fielding, especially in the outfield, is often difficult in these older games that use a ball follow camera view, meaning players have to move fielders that currently on screen. In Steve Garvey vs. Jose Canseco in Grand Slam Baseball this isn't an issue since batters rarely make contact with the ball. In one nine inning game I recorded 23 strikeouts against the computer and struck out nearly as many times myself.
In other baseball video games, I sometimes get frustrated when my infielders automatically move to cover a base when they should be be one fielding the ball. That's not an issue with Steve Garvey vs. Jose Canseco in Grand Slam Baseball because none of the fielders ever move on their own. To record an out at first base, I first have to throw to the first baseman (Done by moving the joystick down and to the right and pressing the fire button. Left and fire throws to the second baseman. Up and fire throws tho the center fielder. Seriously.), then manually run the first baseman to the bag, hopefully getting there before the batter.
Sometimes, with other games, it can be hard to tell which fielder I'm controlling until it's too late and I've moved the shortstop away from a ball I thought the third baseman was going to field. That never happens in Steve Garvey vs. Jose Canseco in Grand Slam Baseball because every ball not hit past the infield grass is handled by the catcher. Even the pitcher graciously stands aside and allows the backstop to field balls landing just pixels away from the mound.
Another problem I often face with other baseball video games is having to individually command each over zealous base runner to retreat on a fly ball. Steve Garvey vs. Jose Canseco in Grand Slam Baseball solves this by conveniently ignoring the rule that base runners can't advance on fly ball outs.
Steve Garvey vs. Jose Canseco in Grand Slam Baseball was a game that was years ahead of its time. I don't think I encountered a baseball video game with this level of realism until the first time I played World Series Baseball 2K1.
