History

Early games used various techniques like isometric projection, mode 7, sprite scaling and ray casting to create the illusion of 3D because true fully 3D rendering just wasn't possible at the time and these limitations lead to the development of a distinct visual look primary seen in 90's FPS games like DOOM and often referred to as "2.5D" because they marked a transitional period from 2D to 3D games that used a combination of elements from both.

Pie In The Sky Engine Games

For brevity I'm excluding most Pie In The Sky game engine shovelware titles from the main list because they either don't exist in the wiki or are hackneyed and horrible.
