The Fairchild VES (Video Entertainment System) was the first console with removable ROM cartridges. It sold very well until the Atari VCS came out.
The Commodore 64 had a cartridge port, although that computer was mainly used with the extremely slow 1541 floppy drive. It was also the best-selling computer in the world for a considerable period of time.
Part of the high expense of the Atari 400/800 and the competing VideoBrain, which came out earlier (1977), is that the FCC required fancy aluminium RF shielding. That drove up the cost of the machines. Jerry Lawson, who developed the Fairchild VES, was angry that this extra cost required Fairchild to price the VES as high as it was priced — particularly since the requirement was dropped not so long after.
I have to disagree with the summary of the NES: Basic but perfectly tuned. When compared with the preceeding consoles in the US, the NES was a huge advance. This was most apparent in the long adventure games like Metroid, MegaMan 2, and SMB 1. The closest thing to that kind of depth of experience in US console gaming was found with Pitfall for the Atari VCS, which hardly compares. The NES also was capable of compelling complex music to go with the complex gameplay. It was a massive advance for the US market and laughable attempts to be competitive from US firms, like the Atari 7800 and XE, exposed how backward US console game developers were. Things were different when it came to US home computer game developers like Richard Garriot.
What was more important with the Amiga than the number of bits was that it had powerful support chips. It was the cooperative task delegation of those chips that made the platform what it was. The Apple Lisa had the same 68000 CPU but no sound chip, no color, and no GPU.
The article doesn’t mention Wizardry, the early iterations of the Ultima series, and Pool of Radiance. There is also no mention of Maniac Mansion, Metroid, King’s Quest, and Dragon Quest (known as Dragon Warrior in the USA). Zelda 1 was also very important.
Particularly notable arcade titles from the 80s that weren't mentioned are Galaga, Pole Position, Xevious, Missile Command, Spy Hunter, Altered Beast, Ghost's 'n Goblins, Rampage, and Mike Tyson's PunchOut. Those were all hugely popular in the US. Berzerk, Paperboy, and Defender probably deserve a mention, too. Dig Dug was hugely successful in Japan. E.T. should be mentioned for being such a financial failure.
