Finally found some time to watch this video. This is really good! The presenter's funny and he's obviously done lots of research. And thank fuck for a video that doesn't ignore European gaming history for once.
On a sidenote, around 19mins in he talks about 3D on the Atari ST, a computer that didn't have a floating point processor. Amazingly enough even the Playstation, well into the era of textured 3D polygons, didn't have floating point--everything was still done using fixed point arithmetic. If you've ever done anything with computer graphics, try imagine doing it all with integers.
