I've had a look on the wiki, but it's only basic and tells you the basic stuff plus placing him in a building. I need to know how to do AI packages and stuff, how to make a schedule and the like. I can do a few basic things such as stats, inventory etc. already. I copied my NPC off another one and removed all his AI packages (I've heard if you make one from scratch something to do with the face can screw up) so he currently just stands there. I attempted Oblivion AI ages ago but I kept having glitches and eventually gave up and partially forgot how to do it now. Is it any different for Skyrim?

Yup there are more tutorials on the wiki. Check out this one for example: http://www.creationkit.com/Bethesda_Tutorial_Packages

Oh, thanks, I didn't see that when looking up NPCs. Thanks!
