I've never played a PnP game before. I probably won't either... From what I can understand, the DM has a bit too much power. At least with AI you know it's gonna be random. It is too easy for human beings to be biased in things like this. But the main reason why I probably won't play one is that I'm impatient .
hmm...I bet there is some kind of program out there that rolls dice...if PnP games use regular dice you could use a simple yahtzee program to take care of it. But, I've never played so I wouldn't know a damn thing about that...just thought I'd give some input. That's if you play next computer of some sort though .
