A couple of years ago, I reduced the 'Game Logs' tab from 10 games to 5 games (to make room for some other player data). Honestly, I didn't know if people cared about this feature until the complaints started coming in, so this change ended up being a good way to find out that it was actually being used.
Baseball Mogul 2020 will include a revamped Game Logs tab, with an adjustable limit on the number of games shown. I've also changed stats like ERA and AVG to show the player's cumulative stat through that game. (Previously, the 'AVG' column would just show the batting average for that game — such as ".600" if the player went 3-for-5). So now you can see how a player's performance rises and falls throughout the season.
If you already own Baseball Mogul 2019, you can see a limited version of this feature by downloading the patch for Version 22.13.
