Extra Credits is a video lessonseries presented by game designer James Portnow, animator/narrator Daniel Floyd, and artists Allison Theus, Elisa "LeeLee" Scaldaferri, Scott DeWitt, and Dan Jones. The series of videos discuss issues pertinent to video games and game studies, particularly discussing issues concerning video game development, addressing the legitimacy of video games as art, and creating intellectual discourse on important issues in gaming culture.
The series was developed directly from a series of lecture videos by Floyd and Portnow, informally known as "Video Games And...", which ran sporadically from February 17, 2008 to April 16, 2010.
The series originally aired on The Escapist from July 28, 2010 to August 10, 2011, before being split off over a financial dispute. Between September 7, 2011 and December 31, 2013, the show aired on PATV, a distribution channel hosted by Penny Arcade, whose downsizing of partner services after the latter date was cited as the reason for the show's subsequent "move" to YouTube, where the show is currently aired. In addition, the episodes have been syndicated on many websites, including ScrewAttack and the creators' own EC Network.
Alpha Waves is an early 3D game that combines labyrinthine exploration with platform gameplay. By most definitions of the genre it could be considered to be the first 3D platform game, released in 1990, 6 years before Super Mario 64. Alpha Waves was released one year before Hovertank 3D, which is sometimes incorrectly credited as being the first 3D game on the PC. It provided the first truly immersive 3D experience, combining for the first time full-screen, six-axis, flat-shaded 3D with 3D object interaction (like bouncing on a platform). Alpha Waves was an abstract game with a moody, artistic presentation, curiously named for its supposed ability to stimulate the different emotional centers of the brain with its use of color and music.
It was developed initially for the Atari ST by Christophe de Dinechin, and later ported to the Amiga and DOS. The DOS port was done by Frédérick Raynal, a notable game designer who would go on to develop Alone in the Dark (often abbreviated AitD), and Little Big Adventure. He has said that his work on Alpha Waves was a major inspiration for the 3D engine for Alone in the Dark. The PC version was also localized in North America by Data East, and retitled Continuum. Infogrames may have also published their own version in the US under the original title, and it was also released as a part of no less than two Infogrames compilations, on which it retained its original name.
