Baseball Mogul 2018 introduced a feature that searched the web for official team logos and major league player photos, automatically downloading them for use in the game.
Baseball Mogul 2019 takes this to the next level by adding 52,000+ active and historical minor league players. The screen shot above shows a tiny sampling of the photos downloaded during beta testing.
