I don't like vampires.
When I started Oblivion (My cousins convinced me) I rolled a Lizard (They told me after I picked him that it was nearly impossible to become a vampire with lizard).
The first time I slept BAM VAMPIRE, second time I slept (Cured my disease by then) BAM vampire.
It is like they are stalking me.
Anyways I want a werewolf to attack me out of nowhere (It is going to freak me out and be a hilarious experience) and turn me into a werewolf so I can kill those vampires werewolf style.
It's your fault, sad to say. In order to become a vampire in Oblivion you had to get hit by vampires while fighting them. What's more, you either didn't see or just ignored the part where it tells you you got the disease. Then you played for 3 days without noticing the effect, and then you slept. It isn't the game's fault. Also, did you just use a Cure Disease spell or potion after you slept? After the 72 hours that doesn't work, but if you did the quest, it is still your fault.
I think they are in, in fact I would bet all my internets that it is true. It is a staple of TES, I just hope they combine the elements of Morrowind and Oblivion (Passing for human in Oblivion, an actual culture and society in Morrowind).
