Great! I like the idea of a intro sound, thanks for the suggestion. The database can already be edited with simple spreadsheet csv files, when starting a new game. That files can be opened with a spreadsheet editor and teams and players can be added. For the future a in-game editor is planned. There are some that already create some files, but it is still in beta and changes to the game in future versions might break the files.
