Retro games refer to video games that evoke a sense of nostalgia, typically those released during the late 1970s to the early 2000s. These games are often characterized by their pixelated graphics, simple gameplay mechanics, and engaging storytelling. Players find a unique charm in the art and sound design that reflect the era's technological limitations, yet still manage to deliver memorable experiences. The simplicity of retro games often invites casual play, allowing players to dive into the fun without the need for extensive learning curves.
