About the Reviewers

Katax Emperore was born in January 1974. Since his childhood days, he loves board games, science magazines, comic books, and graffiti painting. Katax was introduced to the IT world when he got his first game platform, Fire Attack from the Game & Watch series by Nintendo, back in the '80s. While spending hours on it, he became curious about the process of creating games.

As a teenager, Katax owned Amiga 500 by Commodore on which he played hundreds of games. However, one of the games stuck with him, Shadow of the Beast by Psygnosis. He was enamored by the quality of graphics, music, and FX sounds involved in the game. Katax realized that he would like to learn to create such games, and this was the first step. Today, he can design and develop any game on various web pages and platforms.

The Amiga platform created a high-quality gaming experience supported by an advanced hardware architecture that was way ahead of its time. It was a high-profile computer with real stereo sound supported by the advanced Direct Memory Access technology for multiprocessing. On this platform, Katax learned many aspects of programming, multitasking, DMA, interactive applications, I/O port mappings, graphic design, and 3D. When Microsoft introduced Windows 98, he got serious about programming, 3D, and graphic design, which led him to base his education, and later his career, in the IT industry.

Around this time, Katax experienced live performance of digital visual art improvisation, over music known as VJ performance. He was influenced by Jimi Hendrix's style of improvising each track on a live stage. His style visualize forms, colors, and brightness of images and videos, by playing live visual transitions over each pixel on the screen. Katax believes that it's necessary for each game designer/developer to be a part of some art movement or activity because it helps you in your career, both technically and spiritually.

Katax's favorite bands/artists include Klaus Schulze, Tangerine Dream, Hawkwind, and Jimi Hendrix.
