1) Its newer and is really an updated version of WGPFD.
2) It has expanded on WGPFD with new chapters covering a wide sort of topics(AI, Physics-Based Modeling,etc)
3) The CD also has 2 additional books to read once you're ready for 3D.
The only thing that left me disapointed was
that my CD had corrupt demo versions of the shareware.
