Well... and I'll probably get dunced for this...
You COULD go in and edit Scene_Title
so that the screen shows four lines rather than three?
and on that fourth option, have it open a new window with text inside for the various infos on your game... and then when you click it, it would take you back to the title screen (i think)
EDIT: Okay, can't do that that way (evidently... However, I DO know there is a script for adding it.) Also, if you're able to create a map instead of the title screen to start things off, that would effectively give you all the menu choices you could want, as you could simply designate a Panaroma as your title screen, and events to choose the options (incidently, could also make yourself the graphic of an icon of some sort that hops across to each menu option...)
