Yes you can but that's when you have The Sims 3 supernatural which has not come out yet but it will soon!:)
Technically you can't actually make a witch you can make a Sim look like a witch not
You can make them in CAS on the basics page
There is no such thing as a witch on The Sims 3(yet...), but you can cast spells by going on to TheSims3.com, then go to the store and buy Lady Ravendancer Goth's Book o' Spells. Then install it into your game. That way you can cast spells.
Good Question! No you can't, not on ANY ps2 Sims games But if you get Sims 2 Apartment life for PC you can be a good or bad witch!
Witch and Warlock Sims age naturally. So yes, they will become an elder eventually.
Vampire, Werewolf, Plantsim, Bad Witch, Good Witch, Neutral Witch
The Sims 3 Supernatural Expansion Pack will be released in September 2012. In this Expansion Pack you will be able to be a werewolf, fairy, vampire ( more intriguing ), and witch.
Sims have to befriend the witch (make them best friends) and then you can click on the witch, and then click on MORE. . . and an option should be Teach Me Ways of Light or Teach Me Path of Darkness (depending on whether or not you are befriending a good or bad witch).
The Sims 1 and The Sims 2 (including all editions and expansions)
Yes if you get sims 2 apartment life somehow you can.
You need apartment life to become a witch.
At the moment you can't turn into a Werewolf but with Sims 3 Night Life you can be turned into a vampire!!but when the new Supernatural expansion pack comes out September 6th, you can become a werewolf, fairy, witch, and apparently a more 'scary' vampire.******* hope this helped!
