Yeah, now we can play as a proper necromancer in oblivion because of the new spell called reanimate. Which ressurests any NPC and ables them to fight for you. SWEET
Personally I can't get enought of the living dead. And apparently in Oblivion they are making more emphasis on Necromancers, what with the new spells and such but also in the 3 book writers interview from The Imperial Library there will be a book called Exodus entailing the split of Necromancers from the mages guild. That just may hint to a little bit more Necromantic emphasis.
