On the one hand, I would really like to see Witches and Faeries added to the game, on the other hand, my gameplay generally avoids all of the occult stuff entirely. I have yet to actually play a vampire, and haven't really explored anything about vampires in my game beyond learning enough to make garlic stuff to keep them away. Same with alien and plantsims...haven't really done anything with that stuff other than try to avoid it.
That's pretty much been my history with occult in all the sims games, other than being willing to dip my toe into the magic aspect with at least one generation in a generational game. I'd have voted for a more middle ground if it was an option.
