My first game which im speccing at the moment is Xtyped a side scrolling shooter, using 3D art ssets (Models etc). Im at the design stage at the moment, but im giving myself 6 months worth of coding to get it done.
Im still learning using Chads book, so i will stop and start as i go through the book. I aim to complete the book and game together - i HOPE!
If you are interested, my DRAFT design spec can be found on my blog:
Please leave comments against the thread on my blog if you want :)
PS - Im using XNA 4.0 though.
