Some...though I've seen a few box modeling tuts out there for cars and of course, there's the NURBS tuts which are curve extrusions and lofts. Box modeling is the more common method for character work, as it's how most folks first learn to model. Poly by poly or point by point may be close second placers though, with poly by poly gaining in popularity again thanks to Kobly Jukes, Hwasup Song and the like. Gollum's head was box modeled for the film. Any of these methods can work wonders in the right hands, it all boils down to taste. I'm glad Milkshape offers the choice, so folks can see if they like that style of modeling.
