While the above examples are intriguing, where parallel perspective becomes really interesting is when it is not only used but exploited.

Media Art

Before the early 2000s, many games could not efficiently render true 3-D perspectives, so developers compensated by using parallel perspectives, which emulated 3-D without rendering needed. In particular, isometric projections were popular.

A game that stood out to me for its use of isometric projection is Diablo II. In the game’s lore, there is an extradimensional location called the Arcane Sanctuary, and to demonstrate just how bizarre this place was, the designers implemented subtle optical illusions while procedurally generating the level.
