Backgrounds from Unreal Tournament (1999)
As anyone who is into old first-person shooters knows, the first iteration of the Unreal Engine feels utterly different from its successors, and part of the reason is the unique and strangely magical feeling of its depictions of a digital world. While other engines such as the one powering Quake opted for simple, low-resolution bitmaps, the Unreal Engine went all in for colorful, highly detailed skies, often sprinkled with animated clouds and background detail reminiscent of the three-dimensional skyboxes Valve's Source engine became famous for.
