Is becoming a werewolf as intrusive as being a vampire used to be? Or can I just do what I want whenever I want with no drawback apart from being seen when transforming?

It's better than vampire but still some downsides if you would like to know just ask.

I am asking. =)

Or could you point me in the direction of a place I could read the info myself?

A good start but its missing a few things.

Werewolves outside of Werewolf form have a couple properties; they have 100% disease resistance at all times, however they cannot ever get rested bonus from sleeping in a bed.

Also while in werewolf form u cannot use potions, magic, or shouts.

Is it just me, or did the way they added them as being playable, with more and -worse- cons than good pros, mean to really add merely to the game aesthetically to please those who simply stated that they really "want" to be able to play as one, but failed to be at all specific as to their abilities? This is why I love the game Okami, the wolves don't take the crap in the game, they are, suffice it to say, not really short of being the ultimate.

Pardon the random comparison, I just find the extremely severe limitations in all areas to be disappointing, is all... I just hope they look really cool, couldn't do much in three minutes anyway, so yeah, thinking it is pretty much just gonna be to appreciate the cool looks a bit now and then... *sigh*
