Here are some additional thoughts: >> - Suppose I have the Traitor and another Creeper - Death, for instance. >> Someone else fulfills the current Goal condition. Do I win, or does the >> Creeper stop me? > > This seems pretty straight-forward: Yes, Death stops you, so no, you don't win. The follow-up question occurred to me: Does the first player then win after all? I think not: The Traitor steals the win from player A and gives it to player B, but Death steals it from player B. No one wins under the current conditions. Mentioning this thread to my daughter, she thought to ask: - How would the Silver Lining rule -- "Creepers do not prevent you from winning" -- interact with the Traitor Creeper? At first I thought that SL would allow a joint win: it keeps TT from preventing player A's win, but SL would not prevent player B's also winning. But I quickly thought otherwise, looking at the intents: TT says "instead of" the other player, so if A is not prevented then B does not win in addition to A. So, my guess would be Silver Lining nullifies the winning effects of The Traitor. It would still go to the current player whenever a New Rule is played, of course.
