You have a point however what "really" sold the Wii wasnt the graphics, it was the "experiance" you could get with the system.
1) Wii remote has a speaker that makes certain "sound" effects for games.
2) Wii remote has a rumble effect (shakes) (I know others have this too)
3) Wii "comes" with kinect like system as default, and a software ecosystem (because all Wii 's have this)
It might sound gimmicky, but I loved playing Resident Evil 4, on my brothers Wii, and useing the remote to point like a gun at that TV

It just adds something extra to the experiance when your gameing.
Also... with nintendo you know you ll have:
Super Mario games (of all types ei, Mario kart (raceing) / Papir Mario (RPG) ect)
Donkey Kong Country
Zelda
Kirby
Punch-Out
Sonic
Metroid
And the random Oddball that pops up thats decent like:
Monster Hunter
When you buy a Playstation, do you know any titles that are "sony" only that make you want to buy the consol?
Why Xbox/Playstation didnt sell as well, might just be a question of price, but it could also be that "powerfull graphics" isnt enough to sell a system.
