When was there a restricted area?
You could sleep in any bed under certain circumstances (as long as you weren't trespassing).
Not being able to sell quest items was a GOOD idea.
There weren't any items yoou couldn't take.
You should actually play Oblivion before judging it.
I did play Oblivion... beat it... and got bored.
I respect the fact that you don't want to be "punished" for exploring by messing up a future quest, but a lot of people consider that stuff hand-holding.
Of course, if there's a lore-friendly reason why I shouldn't be allowed in someplace, then it's fine. But if the only reason is laziness/scripting... no thanks.
If I had a dollar for every time I was told "you need a special key to get in here" I wouldn't consider Oblivion such a financial loss anymore.
And the thing about owned beds... how about a bounty instead of a text box? That's how they did it in Morrowind. And how is the bed still owned when I just murdered the owner???? :brokencomputer:
And for items you can't take/sell, I mean quest items, which don't even exist until taking a quest causes them to materialize. Just so that people don't accidentally sell it or leave it on a corpse. Boo hoo!
I know that some people consider that type of thing "game breaking." But I think it's more fun to mess up my first few characters and adapt to a hostile world by trial and error, rather than having "bumper gutters" placed everywhere that protect me from ever messing up.
It guarantees you a perfect 100% completion the first time around and kills re-playability and challenge, the way I see it.
