you will want the historical facegen pack for real player images, this is pretty amazing and has thousands of old and new MLB players, plus people are constantly making facegens for new players, check out and you can even create yourself in the game (with a 3D model)

I personally switched from Baseball Mugol about 3 years ago, started by playing OOTP 8 which was free at the time and then bought OOTP 11 because of how much I liked the old version, figured the newest version would blow that away (which it did). I actually tried OOTP because of the ability to customize league awards and the HOF, I am not sure if Mugol has changed but you couldn't do that in the past with it.
