Skip Intro Scene After Playing Once

In my game, you play two into levels, then it gets to the menu.

I want my game to load the Menu level first and skip the intro levels if you have already played the intro levels so the player does not have to play them each time they open the game again.

How can I do this?

Global Values would be one way.

You haven't played before.
Global Value A=0
>Jump to frame 1

You have played before.
Set Global Value to 1

Global Value=1
>Jump to frame 2

You can also rename the values to help out.

Use Marvs example and perhaps also use an ini to back up the values so that if you quit the game you can still get it to skip the intro level.
