"It was at this point that the entire industry moved over to 3D rendering. Sega failed to anticipate this, with its Saturn console, while the Sony Playstation and Nintendo 64 excelled in this area. Subsequently, Sega never made a console again."
BZZZZZT! How can he not remember the actual final console Sega made? The Dreamcast, not the Saturn, was their last; and it did do 3D.
"Mario Bros, an arcade game that was later ported to the home platforms. This first Mario game has most of the elements that we now think of as intrinsic to platform games as it’s a scrolling game world made up levels to be traversed to completion."
Again, BZZZZZZZTTTTT!!! Mario Brothers was not a side scroller. It was a nonscrolling platformer (and I believe the first to introduce Luigi). The game the author is describing is Super Mario Brothers. I would bet he thinks Mario didn't get named until then either (I think in Donkey Kong Jr., he got renamed from his original Jumpman moniker from DK, to Mario, where he was the "villain."
Those two errors do a lot to destroy any credibility this guy has as a writer on classic video game and computer history.
"Game over. Press Redo or Back." (Always thought the gal who did the female voice for TI-99/4a Speech Synthesizer games sounded hot.)
