Thoughts and Ideas about Games and Game Mechanics
Can't really remember any instances where it sticks out, possibly because all the DM's I've had are good enough not to point it out if they do fudge a roll. But even if a DM does fudge a roll, chances are it's warranted. It's just when they do it all the time that it becomes a problem.
In my opinion if they are doing it all the time they might be a bad DM and don’t know how to scale things for the party!
