Packer, if you actually get most of the models from Majora's mask into your torque game, you wouldn't mind branching off that and making Termina after the 3rd day would you? Someone should make a fan game of that, the credits leave plenty of details for what might happen after the carnival of time. Although, I guess it might be too difficult to create events of the same quality.
Now that I am looking at something you said in your forums, are you making Zelda World with the idea of letting others create content on their own servers? Maybe you could leave room open for something a custom mod like that?
