Holy Crap, I'm DMing This Friday! Help me Pick a Setting!

Thought I had another week. Oops!

I'm running AD&D. Got nothin' prepped. Turning to my library o' Gaming Stuff!

Gonna use an other than homebrewed setting.

1. Greyhawk.
2. Blair's Planet Algol.
3. Vornheim.
4. Wilderlands of High Fantasy.
5. Forgotten Realms Greybox.
6. Formalhaut.

Gotta decide, quick!
