I've been a silent member for a while but I have finally invigorated my players enough to get them involved in Obsidian Portal and have been updating and adding like crazy to my campaign as a result of our shared enthusiasm.
I wanted to post a question to fellow DM's and Players. I read recently on Penny Arcade I believe about damage behind the screen. I have played with the idea and my players are a bit concerned about the outcome of this type of mechanic.
To elaborate, I would roll my attacks and then describe damage done to my players with great detail via oratory delivery. Likewise when they attack they can tell me their damage number and rather then explain what hitpoints the monster has left, they get a description of the attack's result. When I attack them, I keep their HP value totals and current behind the screen so they never know numerically how they are doing.
I value any feedback that you folks have to offer about this idea/style of DMing.
