What are the "Custom Start Date files"? The Custom Start File enables you to commence the game after the standard default setup dates, making it perfect for users who wish to start midway through a season.   Note that Marituas is used as the country for this setup, so if you intend to make that country playable, this file cannot be used.   Please note that this file is incompatible with any other Custom Start file and should not be shared on other platforms/websites.
