I like to model with polygons. I model using one of two methods. I start with a cube and delete all but one face and just extrude edges to create additional polygons or method two, on occassion I will also create a general shape using a polygon primitive and then add detail. I guess it depends on what I'm modelling. But I almost always use polygons and I tend to use the first method of extruding edges far more frequently.
...and that is how I saved the world.
