レトロ アダルトゲーム

Retro games is an umbrella term that refers to games that have been released in the past for consoles that are now discontinued, use out of date technology, or that make use of overall aesthetics that simulate older games. The most common examples of modern retro games include those that pay homage to classic games from the 8-bits and 16-bits, making extensive use of pixel art, simple gameplay with limited controls, and chiptune tune music.

Although gameplay for this category is heavily dependent from game to game, most retro games tend to provide a challenging experience due to the influence of the video game arcade era, where most games had easy to play gameplay but difficult to master or complete.
