Do you have a great idea for a new game? If you want to preserve it, fill in order form and send your idea to the Bavarian Games Archive as a deposit!
The document may contain everything which is important for the game, eg. a copy of the rules, the game board, game material, test reports, all kind of descriptions, fotos, etc. In case of legal disputes about the rights, you may refer to this document and therefore also prove when you had this idea and what the content of your game idea exactly contained.
Within the European Economic and Monetary Union, you have to pay 75€ for a 5 year preservation. If you send your game idea from further countries, you have to pay 100€.
