Oblivion Plays A Lot Like Morrowind
I also really like all the fun little UI gadgets that they've installed over the last game. Instead of just "picking a lock", you can actually try to manipulate individual tumblers in a cross sectional image of the lock's mechanism. Trying to raise an NPC's disposition towards your character is represented by a little 4-step mini game representing the types of things you can say to the NPC and how they would react. By the way, the lock picking thing was, I believe, ripped off directly from picking locks in Wizardry 8 which did a similar thing with tumblers: try to raise one tumbler at a time, fail and they all fall down. Oblivion improves on this by making lock picks required, which can be lost each time to fail to set a tumbler, and by lowering the chance that all the tumblers fall when you mess up if your skill is high. This makes me really eager to see if Oblivion also copied Wizardry 8's trap disarm mini game and improved upon it.
