I'm curious to see if there's any way you can set an intro event in rpgm1 and not have the same sequence happen everytime when you enter that dungeon. Say, for example, an intro event takes over to another event to introduce the heroes to the town. Then, whenever you enter the town, that intro event will replay. Any way to stop that?

add a second blank page that relies on a switch to activate, and at the end of the introduction event, turn that switch on.

I (and Valk, it seems) must be reading your question wrong. Surely you already know how to work switches.

Yes, I know about switches.

However, to my knowledge, the intro event will take over to another event. And, if I'm not mistaken, page conditions aren't considered when you take over to an event.

intros only take over if you put the take over event into them.

it should look like this:

Page 1:
events: stuff for intro (include switch x)
Conditions: none

Page 2:
events: blank
conditions: switch x on
