Unity

I have been doing some work in Unity.  For anyone interested in getting started, here is a list of the most useful videos and tutorials I have found:

A recorded live training for 2D character controllers.  Gives a full run down of using the relatively new built in Mecanim animation tool:

Here's Aron Grandbergs site that includes the A* pathfinding project, which is used in just about every Unity project I've seen, as well as other useful tools and insights:

Ray Wenderlich has some solid tutorials.  I also recommend the site for their iOS tutorials as well.  I think the tutorials are particularly good(and I believe intended) for anyone wanting to do mobile games:

Finally, Bergzerg.  He has a great step by step walkthrough of building a complete 3D rpg similar to the latest additions to the Elder Scrolls series.  It's useful either in parts, or for building the full project if you have several days to kill:

I hope this helps anyone that is looking for suggestions on where to start if they want to make a transition to Unity.  I particularly value it's cross platform ability.
