Traveller Werewolf - more games planned
Still have werewolf games in sign-up.
It's an interesting idea, but I'm not sure secret movement would really track with TI:3. You have the issue with the role choice providing some information, the Victory Track being fairly opaque lacking vision, and combat really isn't designed for it. Fleets really can't be purposed well for scouting/combat/colonization in their chunky granularity.
Now, something like Space Empires: 4X would be much better suited for such.
That is another game idea I have been developing, but using Starfire rather than SE rules. See here - just waiting for enough interest
