Depends on the rendering software, from what i've seen. if we're assuming Koikatu for the 2D stuff, then if we stick with Illusion for the 3D as well (Honey Select, HS2, AI Shoujo, etc) then there's no real difference in rendering difficulty -- jsut a matter of the dev's preference. On the other hand, if we still use Koi for 2D but switch to DAZ or Blender for the more realistic 3D, then yeah 2D is way easier, because DAZ and Blender are far more complex, and DAZ at least can take hours to render a single frame. Potato/potahto, more or less3d is better but more times there is a 2d game that is graphics good and story good. Easier to make perhaps?
