During the forum discussion where I posted a copy of my approach to lock picking, someone responded that it looked like the 3e/4e approach, that he couldn't see any fundamental difference. I tried to clarify that the difference, as I saw it, was that I assumed any attempt to pick a standard lock is successful, but that when an opponent is trying to finish their action before the lock is opened, I would roll to see which finishes first. This may or may not prevent the lock from being open. In contrast, 3e/4e makes a skill roll to determine if the lock is opened at all; this is true of opening locks even when there is no time element.
He still insists that he sees no fundamental difference. Either he's playing 3e/4e in a very different way, or I'm not making myself clear, or I'm not understanding what the 3e/4e rules seem to be saying, since they explicit mention that locks remain locked on a failed skill check.
Anyone have any insight into this? Am I really describing stripped-down 3e/4e?
