I came to post about Dune PBEM and found this old stickied thread. We haven't had a chance to play Dune ftf for some time due to lack of players and I was wondering what PBEM solutions are there. I'm eager to give anything a shot if there's interest.
Someone did a major revision of the Dune module using Scott Everts' art from BGG. I haven't tried it so I can't vouch for whether or not it's easier to use, but if anyone wants to take a gander: www.vassalengine.org/wiki/Module:Dune
