Supernatural info

Hello.

I am a long-time Sims 3 player, but haven't played the Supernatural expansion - even though I had downloaded it years ago.  I have read some of the gameplay info and know what characters are introduced (or in the case of Vampires from Late Night, re-introduced).  There seems to be a lot of info to absorb.  Though I have read general posts, I don't know where to begin.  I know that this is a broad inquiry, but any advice will help.  Thanks.
