The unrealism in this game is ridiculous. Several things right off the top strike me.
AI ability to hit foul balls and run my pitch count up. Opposing batters rarely ground out or fly out quickly. I easily get to an 0-2 or 1-2 count but then the BS kicks in. The AI fouls off the next 5 to 7 balls. Every inning is 15 to 20 pitches. Even if I purposely throw as far outside as I can, they still make contact. Every game I am replacing my pitcher in the 4th to 5th inning because the pitch count is in the 80s or 90s.
The amount of fielding errors. I can expect an error 1 out of every 3 to 5 throws to a base. No team has 3+ errors EVERY game. I use the pure analog control and simply flick the stick in the direction of what base to throw to. Outfield to infield, infield to infield, outfield to cut off... doesn't matter. I have 3 or more fielding errors every single game from throws going bad.
Diving / climbing catches. AI pulls off 80% of their diving catches. I have yet to complete a single one. The rule of statistics say that I should have completed one accidentally by now, but I come up short on every single dive.
For our only option for a baseball simulator they do a [censored] poor job of "simulating" realism. It would be like calling Twisted Metal a realistic driving simulator.
