Am I the only one that liked the fallout lockpicking better than oblivions?
The lockpicking in FO3 was just a different animation, using a newer type of cylinder lock, instead of the old "tumbler" designs. That modern type of lock wouldn't be at all "fitting" in TES. In OB, the actual difficulty of the lock didn't vary by much, if at all, with difficulty, other than by adding more "layers" of tedium. In FO3, the biggest functional change was adding a minimum requirement, but it still didn't make a "Hard" lock noticably harder than a "Medium" lock.
To make Lockpicking skill actually meaningful, the speed and sensitivity of the tumblers should reflect the DIFFERENCE between your character's Lockpicking skill and the lock's difficulty. A skilled thief attempting to open an easy lock should be almost automatic, and the tumblers should react lethargically, almost as if they're in thick syrup. A novice thief attempting to open a difficult lock should be faced with an almost instantaneous snap-back of the tumblers, making it all-but impossible until your skill improves. It shouldn't stop you from trying something far above your level, if you really want to go for that off-hand chance that you can get it "just right", but it really should be close to pointless to try. When the game tells you "you don't have the skills to try", as in FO3, that's immersion breaking.
Oblivion's locks were about in the proper difficulty range for when your character skills match the difficulty of the lock. Problem was, it was that way no matter what your character's skills were.
None of the poll choices really address the point; making them all harder or all easier just ignores the underlying problem that your character's skills don't make any difference.
