Most "bishōjo" games remain 2D. The main reason is that "bishōjo" games are centered mainly on characters instead of landscapes, and for this intention, 2D bitmaps continue to look better than 3D models (which tend to be blocky when seen up close). The main advantage of 3D models in this context is smoother and more realistic animation, although this is usually discarded by the unpolished look of the 3D characters, in addition to the additional cost of production for this type of work. "" (2001) was the first "bishōjo" game to have all its characters modeled in 3D, although the sales were smaller than hoped, perhaps discouraging other developers from the possibility of changing "bishōjo" games from 2D to 3D. Many "bishōjo" games nowadays are essentially a slideshow of 2D pictures plus voice and text.
