References to Sega/Video games

Back to: References to Sega.

The success of Sega's multiple video game franchises has resulted in the company becoming one of the world's most-recognizable video game developers, and established a legacy which continues to grow to this day. As a result, references to Sega have appeared in a number of video games, including those developed by other companies. Titles like Space Harrier resulted in a boom of rail-shooters for other platforms, such as Alantia for the PC-88 and Jinmu Denshou for the PC Engine, among many others. Additionally, the success of the company's Super Scaler arcade titles paved the way for titles like Taito's Galactic Storm and Top Speed, and served as loose inspiration for later titles like Night Striker.

Sega has also directly included its past franchises in titles like Sega Superstars, Sonic & Sega All-Stars Racing, Sonic Pinball Party, and others, while rhythm games like Samba de Amigo feature songs taken from past titles like After Burner and OutRun. Other titles, like the cult favorite Segagaga and the Project X Zone series, build themselves around these inclusions, with later franchises like Sega Hard Girls taking this idea to a new level.
