In fairness when I look at these lists I never agree with the order usually so I just consider the games listed as a whole and decide would I list them in my top 10. Given the huge number of people I know that have sunk in excess of 50 hours into Oblivion I actually agree with rating it number one this time. As for the rest I've only played through Fallout 3, Mass Effect and Fable 2 so I'm incapable of assessing it properly.
