I plan on getting FCOM and Open Cities but aside from that I am not sure what to get, I would like a mod that expands on magic in some way, more spells and the like, is there a good mod that adds werewolves? Or expands vampires?

I think there was once a mod improving the Wizards Tower, is that still true?

Any recommendations for mods that are considered 'must have' would be great.

Are there any survival mods? Are they fun?
