What about a combination of things?
Software... WiiFit, WiiSports, Mario Galaxy, Smash, Zelda, etc.
Hardware is sleek and sexy
Peripherals/Controllers (some actually serve a purpose) and work
Affordable
And cool (to normal people) with great advertising.
It may not be the best at any one thing (except maybe periphs) but it's a combination...
PS2
Software MGS, GTA, Madden (Remember at first PS2 was the only one with online play, because EA was anti-MS), ZoE (big early gen game), Final Fantasy X.
Hardware: Black was cool in 2001, Smaller than Xbox, Not purple, no handle, DVD out of box (when many still didn't have a dvd player).
Peripherals: DDR (PS1&2 First), Karaoke Rev (Again First on Sony), Great standard controller.
Affordable: $299 (more or equal to the competition but not $500 either)
Cool: PS was the coolest gaming machine around by 2000.
I would cite regulation, but I know you will simply ignore it.
