Once we were out of the drab sewers, we opened the door on an immense, seamless world that was full of color and life. More than perhaps any other element of the game, exploring Oblivion's amazing world is something that truly must be experienced for oneself. You'll likely marvel at everything from the swaying grass of the wide-open plains to the shimmering lakes that dot the landscape, as well as the fact that you can go virtually anywhere you please. There's a full day/night cycle in place, too, and we were taken aback when we walked out of an abandoned mine to see the pristine night sky for the first time.
