alanback: How? Like you said, It satisfies monkey curiosity. But you said it was only monkey curiosity, which value cuts your off from understanding it's experiential benefit. I love knowing what my opponent's dice are when I play at Gold Token and DG (when the move-ahead hasn't stopped on my turn). But, then again, I am a very curious, er, bunnkey!
Another reason, though it wouldn't apply to many people, is that feedback is of most benefit when it immediately follows a behaviour. Thus, by seeing the dice immediately, you can tell if your spell or sacrifice to the Dice Gods worked or not.
