Perks
Lockpicking, except you can open any lock
Speechcraft, except you can't see the chance of success
The amount of spells you have at your disposal is probably about the same as an average of Oblivion and Fallout
Do you mean Fallout or Fallout 3?
Lockpicking in FO3 is essentially the same as Oblivion; all that changed was the method used... It actually got simpler from Oblivion's.

For an advancement on Lockpicking, I would have expected a more interactive 3D system that let you pick the lock... Something similar to this >> http://i271.photobucket.com/albums/jj125/Gizmojunk/lock4.gif
