Any list that contains Final Fantasy XIII must be trolling. It's easily the worst RPG I've played in a very long time.
I agree with Tsar, New Vegas was better than Fallout 3.
And then where is Mass Effect? And Dragon Age? And Kingdoms of Amalur Reckoning (haven't played it yet but apparently it's very good)? Divinity: Original Sin? All of these games are better than Final Fantasy XIII.
