Since Queen Games owns a patent (and pays for it every year) on their "cube tower," they are desparately seeking a new "big box" game using the device as a central mechanic.
The tower was previously used for the games Wallenstein (and it's remake, Shogun), as well as Im Zeichen des Kreuzes.
Unlike these previous games, however, Queen Games is specifically looking for a new game that does not use the tower to resolve battles.
The other requirement is that it should not be possible to use cards or dice to duplicate the mechanic using the cube tower (in other words, the game should be something that can only be played with the cube tower, making it a central mechanic).
A word of warning, should you choose to make a submission: Queen is notoriously slow in responding to game designers.
I'm afraid that's all the info available. I received this tip from friend and designer Peer Sylverster ("King of Siam") who has been submitting some games to Queen.
From what I understand, the tower needs to be used "as is" with no major modifications. It can be docorated with different art, of course, as it was for "Shogun."
If you can develop and test a prototype that uses the tower, email the rules to Queen Games and attach a photo of your prototype. Of course, you'll need one of their games in order to use the tower for your prototype. And, there's some risk involved--since they have the patent on it, you won't be able to shop your game to anyone else if it's rejected!
