I don't understand how people could say games like Fallout 3 or Dragon Age are the worst games they've ever played. Sure, you might not like them, but you've
really never played a worse game? 
I am being increasingly mystified by the mention of those, Oblivion, the Fables etc; they're all really pretty good games (yes, even DA2) whether or not they're to our personal tastes. Although I mentioned Skyrim as my most
disappointing game of late, I don't think I would be taken seriously if I tried to claim it was genuinely bad.
There seems to be quite a lot of "I don't like it much" and the perennial "Oblivion lol" in place of things that are genuinely awful.
