I see PS2 mainly as a continuation of PS1 - PS2 just saw Sony learn the lessons of how to build a perfect developer ecosystem and game format from PS1. Nintendo was new to diskbased formats and had to learn how to balance things. It is similar to how SNES and Genesis just expanded on the development of the NES.
You can tell from the growth of the industry when features are added that people like.
Atari - NES 2x growth
NES - SNES/Gen 20% growth
SNES/Gen to PS1/N64/Sat - 2x growth
PS1/N64/Sat to DC/PS2/Xbox/GC - 20% growth (estimated..PS2 still selling)
DC/PS2/Xbox/GC to Wii/360/PS3 - logically, this would see 2x growth..to 360 million units sold!..I suspect it will only grow to 200-250 million though...
People are difficult to govern because they have too much knowledge.
When there are more laws, there are more criminals.
