Which are the best, easiest to follow and most useful tutorials here for a Unity beginner ?
Start with the 6 little intro style movies on the Unity site. Then this set by Ryan is also great for getting a feel. http://forum.unity3d.com/viewtopic.php?t=26808
Then if you’re on a roll, I’d try out the 2D then 3D tutorials in PDF form also on the Unity site. After that, you should be ready for Will’s Unity tutorials. There’s plenty to get you going. Good Luck!
