Thanks guys,
My son is 9 1/2 years old and already a computer whiz (like his dad.

) His level of knowledge is quite high and he buries his head into this stuff and just drives right through it. He is actively using 3d game maker and has basically ran what it can do into the ground and wants something more now so I started searching and found this software, downloaded the demo for him and he was off...
He has done a lot of 3-d modeling in lightwave, programming in VB and is already writing his own story boards for movies and games. We got him a video camera a few years ago and he has even been producing, shooting and editing his own movies too.
The cost of the commerical version is not terrible, but I was not sure if he would get the full use out of the addtional features right away. What do you guys think would be the primary difference between the Extra version and the commerical that he would really miss out of the gate?
Thanks Again for the quick responses!!!
