3rd person in oblivion is terrible.Gameplay is not your standard fp rpg.You can swing melee weapons,block with them,and use magic,staves,and bows in the most realistic large environment that you will probably ever find in a videogame.I would definitley recommend buying it.You can't really compare it to the games that you mentioned or any others because its just so unique.Better than Morrowind by a long shot.A must own 360 game...
