to answer the cost question:

the book doesn't have a set price yet of course, but i'm estimating the book, with the CD of resources, tutorials, a6 trial version and such, will be around $30-50

i'm also thinking of selling like a .pdf version of the book , so it wouldn't come with a cd, and that would be around $25, but i think everyone agrees that it would be more useful if it was in printed format with the cd, it'd be easier to find stuff i mean.

and i just checked my emails and JCL said that covering newton's physics engine rather than 3dgamestudio's is fine.
