So basically, Tilly, you want: True soft shadows with umbra and penumbra calculations, global illumination, cube mapping, phong reflection model, real motion blur, HDR, and subsurface scattering.
I want these things as well.
I really want these types of features for the gamers with high end PCs, on lower end PCs the effects can easily be turned off.
Soon, I'm going to compile a list of everything I want in the next game, it's going to be huge.
