Summary: This game is open, exciting, and cool. It's not quite as sharp as Skyrim which came after it. If you've played Skyrim you will miss things like the "run" button here. Still, Oblivion was a huge leap forward and I have played through the main story more than once, and the side missions / wandering tons of times.
Summary: By far the best game of 2006, and still an awesome game. No matter how it's played, it is impossible to play the same way more than once. Every time will be different. I love it and I still play it. The Steel casing looks great on my Elder Scroll shelf. I'm willing to bet it's gonna look great on your shelf too.
