So, what is/are your favorite genres/sub-genres that are currently DEAD? Also explain your favorite games (or franchises in that category).
My choice is the sci-fi/futuristic racer. While other parts of the racing genre (Kart Racers, Simulation) are still alive and well, sci-fi/futuristic is pretty much gone. Nintendo hasn't published an F-Zero since GameCube/GBA and refuses to do so due to business reasons. Acclaim (Extreme-G publishers) is out of business. Lucasarts only put podracing in Star Wars Kinect instead of a third pod racing game (the first was on N64, Dreamcast, and PC while the second was PS2 exclusive), and Sony shut down their Liverpool studio (formerly Psygnosis), who developed the most popular Wipeout series.
