As a hugh fan of WFRP, and a big online player also, it crossed my mind, why - since the Warhammer game is made as a MMORPG (like World of Warcraft and others), it could be a nice touch to have either a DVD or a CD-ROM made, with a thourough journey through the old world.
Imagine the same piece of work, that was made after the Lord of the Rings Trilogy was released. There the producer made a completely seperate DVD on Middleearth (and probably made a bundle in doing so).
So ... as a suggestion: Make an Old World DVD!
If you need me to explain furhter, please e-me!
