Hi Darkhog, and welcome to the forums, Mapscape is free, and much easier than Blender to use. it is practically similar to 3DWS as well...
Yes, DarkPhysics [PHYSX] is included in the bonanza deal and works pretty swell for most uses...
If we or I can be of any help, just shout out
have you got yourself texture programs as well? there is GIMP and Paint.NET...
