I liked that morrowind wasn't nerfed. The game created some basic rules and if you were smart to mix and match (i.e. potion quality scales with int, and int potions are additive, so boost your int like crazy and then make amazing potions) you could overpower the game. But that was the fun part. Compared to morrowind, oblivion was on rails. I still remember the sheer awesome of going into a cave way beyond my level. Realizing it and then using a cheap levitation potion to get our of harms way and rain down arrows and getting mad drops. Or using some seriously overpowered spell tricks to sneak into the underground vaults beneath vivec. And never did the game give me a "sorry this puny wooden door needs a key. Unlock 100 no workies!"

You've misunderstood the use of the term guilty knowledge. In this context it doesn't mean the participant feels guilty. Guilty knowledge could have been showing you a picture of an apple that you'd previously seen.

This would have been obvious if you had read the article. No guilty knowledge for you!

That's a little disingenuous. Given the console is 5 years old and this is the first significant and, dare we say, optional upgrade. It's really not so bad. Particularly given that people spend upwards of 300-500$ for video cards (double that for SLI) and they do this much more often that 5 years. Let's not get into the motherboards that have to house these puppies. Hell, people's PC cases are more expensive and upgraded more often than their consoles. I've upgraded my computer twice since the xbox launch. I'm sure I'm not a minority there.
