Saturn and Playstation launch dates are 1994 if you're factoring in Japan. And the US Dreamcast launch was *late* 1999, and was very much an active platform in 2001... Also the Dreamcast didn't kill off the Saturn in Japan either, the Saturn was still kicking pretty well in Japan (dead in North America however), in fact the Saturn was Sega's most successful platform in Japan.
I am an American, what do you expect? The world revolves around us
From how we "got" the consoles:
1995 PS1/SS
=> 1 year
1996 N64
=> 3 year
1999 DC
=> 1 year
2000 PS2
=> 1 year
2001 GCN/Xbox
=> 4 year
2005 Xbox 360
=> 1 year
2006 PS3/Wii
When you start adding in the Japanese numbers, especially PS and SS, I guess it does begin to sku it even more, as you noted, and does make it hazier.
You gonna consider the PS2 in between as well?
It is a successor of the 5 year old PS1 and, with the benefit of looking back, was the beginning of the 2nd 3D generation and has remained the baseline. The DC didn't quite live up to that.
Or consider the 360 an "in between platform?"
No, for all the opposite reasons given on the DC. Not only is the gap larger but it is also clearly a next generation device matching the competition in memory and general performance envelope.
I can see where you are coming from, as the DC is 3 years from the N64 and 4 years from the PS1 but only 1 year from the PS2 and 2 years from the Xbox1 and GCN. Adding in the Japanese numbers does, as you mentioned, show the DC much closer to the 2nd 3D gen.
But looking at the hardware and games it definately did not live up to the PS2/Xbox/GCN baseline (whereas I think it is pretty obvious that the Xbox 360 does compared to what the 3rd 3D gen has).
Maybe a better label for DC: Tried to jump start a new generation and failed and left the market.
What makes me view it as "straddling" is the fact its short life cycle, at least in the US, have its life split between the two. They ended production in January 2001. Lifecycle of 1999-2001. (Edit: 1998 if checking Japan--only 2 years after the N64 in Japan). It was dead in the market before the GCN and Xbox1 even shipped.
I guess I see it as shipping a couple years after the N64, but a couple years before the GCN/Xbox1, and it died before the later even got to market. And when comparing consoles, the PS/SS/N64 share a lot of traits, and the PS2/Xbox/GCN share quite a few, clearly "generations". The DC is closer to the later, but also is lacking pretty much across the board.
But maybe you are right.
Either way, adding in their 10M sales would be 15% growth in this last generation.
Still a HUGE gap from 100% growth.
