I have to say, the more I play this game, the more disappointed I get.
The main reasons are fielding and baserunning.
Fielders often act like they are in pee-wee league. For instance, a routine throw to first will often have your fielder diving to catch it, or drop it.
Base-running is far and away the most frustrating thing to me.
For instance, you have a runner on first. You hit a ground ball way into the out field and the runner just stands there. After it happening a few times I thought "Duh it's probably because I have to make him run". A LITTLE better but the runners often stand around or steal bases by themselves with 2 outs, or something else to make you slam the controller.
Hitting is pretty good. It's straight forward, if you've played a baseball game, then you'll know how to hit.
Same with pitching.
Overall, you can drastically tell they tried to make the players less skilled than most pro's. Which, while is bearable/fun during batting and pitching, is absoluetly mind-numbing during baserunning and fielding.
