The graphics are really what make this game stand out over the others. Never will you see such cool and accurate views of the various stadiums in the league. The game gives a little fly in as you start and the stadiums are indescribably awesome. I have been to enough ballparks to know that the developers spent a great deal of time making these stadiums as accurate as possible. The in-game graphics are pretty good as well.
All players are polygons that are fairly representative of the true-life models.
Most of the batters' stances are accurate and everyone looks pretty good. The field during the game looks real, but the distances seemed a bit short. What I mean by this is that when the catcher threw the ball back to the pitcher, it feels like he barely threw it. The same goes for the outfielders throwing back into the infield. Triple Play 98 is a slightly better than the average playing baseball title in a year full of average baseball games.
