I, too, love Oblivion, but it does have issues. General bugginess, not-very-good voice acting apart from Captain Picard, Boromir, and the Prophet of Truth (Uriel Septim, Martin Septim, and Mankar Camoran, respecively), etc. And the "stupid conversation pie" i.e. the persuasion minigame is completely useless once you get the ability to create your own spells and just create a spell of Charm 100 pts for 3 seconds. It eliminates any need for the pie, since you can make anybody love you for the duration of the conversation, and it's very low cost as well.
