Using nottud's recent discovery about main menus, I was able to create this main menu which completely changes each time you click a button. This can only be viewed using Nottud's Redisigned Main Menu. The Redesigned Main Menu can also be downloaded with Nottud's Ultimate Editor Superpack. Once you have put ~menu20.scx in C:\Program Files\Microsoft Games\Age of Mythology\scenario, open the game, click the 'E' button in the top right hand corner, and select ~menu20 in the top dropdown list.
The Tartarian Main Menu mod is a set of new menu backgrounds for Age of Mythology: The Titans, featuring various scenes created by our very own TartarianCerberus. The mod features a new scene for each button clicked in the main menu, following Nottud's interesting discovery.
