Update #29 brings custom roster support to the game. A couple of users were talking about the need for custom roster support this morning, so I worked on it today to get it implemented. You just have to use a CSV file from Excel or Google Sheets and you can generate full universes, dynasties, or just a few select players. The game will auto generate any other players that are needed.
You will import the roster during the team selection screen. You will get a message on how many players were imported and how many teams received new imports.
