Well, like someone said, out of the consoles you listed the Saturn would be the most interest comparison. I was interested in platform that at least had some market presence or awareness. Sega, Sony and MS platforms.
Atari was huge in the '70s and big in the '80s, though. Their story was different from Sega, however; Atari had more of a long, slow decline, not the sudden collapse of North American Sega... though the Atari 5200 was a pretty big failure, going from market-leader with the 2600 to 1 million sold with the 5200. Atari did recover somewhat with the 7800 (3.8 million sold in North America, similar or better numbers in Europe), but after that... yeah, as I said in my last post, the Lynx didn't sell too well, and then the Jaguar failed pretty badly.
Still, for examples from the '90s or newer, the Saturn might be the best example, yeah. Sega went from market-leader in North America and Europe to near-irrelevant in both pretty quickly. Selling 1/10th (or less) of what your last system sold in that region... that's pretty terrible, but Sega managed it. I think Nintendo can avoid THAT (hopefully!), but Wii numbers... those do look extremely unlikely.
Well comparing raw numbers is at least interesting, like you said even with a smaller market and with the red hot PS2 dominating, the GC so far is putting better NUmbers than Zombi U
Yeah... that's not good for Nintendo.
I do think they made some mistakes with the Wii U, and we'll see if they can fix them, but as a Nintendo fan, this is not good to see.
saturn would be better. dreamcast came out around the time npd sales were being regularly revealed every month, but a lot of that data's been lost to time.
Forget monthly sales, for Sega's consoles even the worldwide lifetime totals aren't definitely clear.
