+	// the intro is shown and then when the first scene is shown, there's a dialog
+	// thanking the user for playing the demo and asking him to buy the full game,
+	// without allowing him to continue any further. The game data itself for these
+	// demos does not contain any scripts for the first scene (i.e. there's no text
+	// in the game data to look at Rif's silver medallion). Also, there are no more
+	// scenes apart from the Grand Tournament scene. This opcode is called in those
+	// demos, and I assume that its use there is to just show the popup window and
+	// exit the game. Therefore, once this opcode is called in the older ITE demos,
+	// exit the game. Known non-interactive demos are GID_ITE_MACDEMO1 and
