We've seen a surge in the popularity of monochrome game art in recent years. Like in film, what was originally a product of necessity is now a deliberate stylistic choice used to evoke atmosphere, nostalgia or emotional intensity.
It's a sign of how popular monochrome game art has become that Steam's currently hosting a dedicated sale event. The Steam Monochropoly festival runs until 3 August, showcasing a host of creative game made using monochromatic or significantly restrained colour palettes.
