And make the game more mod friendly.
Take a look at the SH series. The game survives very very long just by let the community do a great part of the work
Even a good campaign isnt needed on initial release. Just provide us a Editor and the Community will do the rest (or build Campaigns and make them DLC for some extra bucks).
Edit: i would love something like an interior of the ships. What i really miss at the whole DW is just the feeling of sitting inside of the Boat.
I think thats an important thing because of the flavor.
