Much as I love Sweet's work I also have to think of this. Maybe we could get portraits as stretch goals from whomever they are getting their art from now?
If they can afford to put in a co-op or multiplayer experience I'd go for it. Of course I'd want it after everything else for single player had been implemented. . . but my partner and I have been trying to play IWD together and its been fun replaying it with someone else.
