As do many of Bethesda's methods of releasing information about their next big game.
Like this concept art for Fallout 3:

Ohforget you.
Now I have to go play fallout.
I'll probably not play through the whole main story for like month at least.
I never beat Oblivion until like 2 years after I got it.
I just do a bunch of other quests.
Sadly the same thing happened to me.
Lol. My first character got lost in the ruins across from the exit of the sewers.
I spent a day trying to get out xD
