They should be lvl 3 to give them a snowballs chance. As the Worms AP uses the 3.5 xp chart (13 encounters per level) and the PF chart is loke 20 encounters, I have/am adding in side stuff like Mad Gods Key, Dymrak Dread, and bandits to even it out. I also am planning on having them find a collection of maps with notes they can have translated so I can use the cardstock, single page adventures that came in my Greyhawk boxed sets. Lots o' tombs in there.
I am figuring on the players being lvl 24 at the end. Granted, thats a rough guess, but since I tend to make things tougher since they have 6 PC's.
I should prolly post my campaign progress while it's still fresh in my memory.
