Without some fancy scripting, WFRP3 will not appear on Fantasy Grounds 2. The dice routines for FG2 are notoriously hard to get at and they just aren't set up to handle icon dice. Plus, Smiteworks just changed hands. There's a new programmer in town. It's hard to tell what direction he will take it in at this point. He seems to have a lot of plans.
Ideally, he will try and cut a deal with GW and FFG and make an official ruleset. Heres hoping! If I could get official permission from Fantasy Flight, I'd make a ruleset for Fantasy Grounds II that would allow online play (with full rules, or a rules light version).
I play WFRP2 and D&D4 on Fantasy Grounds II every week and I really hope some deal can be reached for WFRP3.
Dear Fantasy Flight Games,
I would officially like to open negotiations to create a full ruleset for the Warhammer Fantasy Roleplay system on Fantasy Grounds II. I have not, nor will I write any code for a ruleset without express permission from Fantasy Flight Games, however, I have some ideas if you are interested. You can contact me via PM or through my forum listed email.
