How To Make A RPG Fantasy Game

http://unity3d.com/support/resources/tutorials/3d-platform-game.html is a very good one most likely fits your needs

There aren't any official tutorials specifically for 3rd Person RPG's but there's a couple for 3rd Person gameplay, like this 3rd person platformer here, and this 3rd person shooter here. They won't be exactly what you're looking for, but would hopefully prove to be a good base to start from. The platformer is a full blown tutorial with a project and .pdf tutorial, whereas the shooter is only an example project, to use as reference. There may be unofficial tutorials that are closer to what you want though, here's a good start, and google's always a good bet!

Good luck!

For anyone coming to this question lately: this link is 504'ing. But you can find the videos here: http://www.youtube.com/playlist?list=PLE5C2870574BF4B06&feature=plcp

I've really enjoyed the RPG Tutorials done by InsurgentX: http://insurgentx.com/game-development/

They focus on a Final Fantasy 7 style turn-based game, but you will definitely get a LOT out of them for any RPG style game.
