This sounds interesting. I like that they are putting all the madness into the game again - magic, witches, werewolves - all that. I didn't really play Apartment Life (the magic EP) in Sims 2, but Seasons (which had plantsims in it) was one of my favourites, so I like the idea of this a lot. I agree with Fez when she says that Sims was meant to be weird. It's a realistic /real life simulation/ game, yes, but one of the biggest (also bestselling) add-ons of this franchise were supernatural-oriented. I personally think that that's what video gaming is about anyway but that's another topic of discussion.
To put it short, I like the idea of this EP. Also, I think SimPrograms shouldn't be all that sure of it, just yet, but...eh. I hope that this rumour is true.
