For the non-gamers, the Wikipedia link:

This article does explain a part of why I find 3D games jarring and peculiar, though; I could never get past how odd corners in games can look (e.g. when they are right behind a lamp that somehow doesn't reach them).

Just didn't know this is what it was called.

Frankly I prefer the era where games didn't try to do this.
