All told, this is the closest thing you'll get to an actual pitcher-batter confrontation, without actually showing up for spring training. With all of the praise that has been heaped upon this aspect of High Heat, it's an area that is hard to improve upon, year after year. 3DO could have sat on their laurels and left the gameplay alone, and it still would have been praised. Ahh, but that's not how these guys operate. Some minor tweaks were applied to further distance the game from a slew of other baseball titles.
Errors are more varied, and include very believable throwing mistakes.
Diving infielders can throw from their knees as in the past, but this year, they don't always attempt a throw. The variety of hits has also been expanded. Ground balls have a little more bounce than years past. These may not sound like major changes, but when you're so close to perfection, there's not much else you can do. Probably the best thing they did to the gameplay was not changing it to the point where they actually altered the way the game plays.
