This tool allows you to manage different game configurations.
-Have a separate game configuration with separate custom content for your (for example) medieval/zombie/futuristic world
-Change the game language
-Create a small game to test things or create content without waiting for hours to load everything
-Easily create content that requires only the basegame or only some EPs, so you don't have to worry about items from other EPs.
-Test mods and custom content in a separate profile to make sure you don't corrupt your main world
-Manage different mods and savegames for different people using the same computer
