I can understand why you chose to be a vampire. They are more "my style" too but I really hated my playthrough of a vampire in Oblivion. I HAD TO WAIT FRIKKIN HEAPS OF TIME B4 I COULD DO ANYTHING!
So that kinda put me off... Also, i'm finding that being able to change whenever i want will be cool ^^
Storyline: Get married, contract lycanthropy, get home, check where the wife is, wait till full moon, transform, untransform, go home, find wife outside the house, yell: WTF DO YOU THING YOUR DOING OUTSIDE THE KITCHEN!!??, wife tells you she wants a divorce, transform, maul her, make her transform, tell her what a BITCH she's been (hahahahaha), divorce, marry some vampire babe, introduce her to ex-wife, watch as they fight. And all the while laugh as they fight over you.
THE END.
