Still, that minigame was incredibly easy.
Yes, I never understood the Oblivion system, where you weren't excluded from difficult locks if you lacked security skill. In Morrowind, a formula tested both your skill and the quality of your lockpick against the difficulty of the lock, and you had to pass that before you could even try to open the lock. You could be quite skilful, and still not have a good enough lockpick for the lock.
Anyway, why can't my Orc bash open that flimsy chest with his great big axe?
