Good late evening old schoolers!
I always like to remind con-goers that the Old School gathering is also open to those who cosplay from Pre-2001 video games. In fact the first year I attended the gathering we were cosplaying as Taizo Hori and Masuyo Tobi from the classic arcade games Dig Dug and Baraduke. As long as it's a game character from before 2001, it's good to go!
With that in mind, how about an OP from a video game that looks as if it were based on a vintage anime series.... but isn't? 70's Robot Anime Geppy-X was a 1999 Japan-only PlayStation side scrolling shooter framed around being an homage to 1970's super robot anime. Spanning four discs, it didn't just go for a visual aesthetic in its gameplay. Each stage features an opening and ending sequence, animated insert scenes, tons of voice work, eyecatches that lead into commercials for merchandise related to the "show," parody advertisements for other anime series that don't exist, and a bunch of songs throughout. Speaking of songs, they are performed by Isao Sasaki, who sung so many old school themes including Space Battleship Yamato, Neo Human Casshern, and Getter Robo.
It's all pretty crazy! The developers basically made a 70's mecha anime series, complete with all the trimmings, in video game form.
