query: What is 2.5D perspective in video games and virtual reality environments?
answer: In video games and VR, 2.5D perspective (also called pseudo-3D) refers to gameplay restricted to a 2D plane with limited access to a third dimension, even though the environment may appear 3D.  It can also refer to 2D graphics techniques used to simulate a 3D look.
