for this gen:

PS3 because of Blu Ray player :)

PS1

NES,


followed closely by dreamcast the first real online console/ also the preview of MS involvement in gaming,

NES

NES if you say otherwise you dont know anything

NES, of course.
For you guys saying PS1, do you mean the most influenced? Because if so, then I agree. I mean talk about rip off.

NES
Anyone who says otherwise don't know wtf they are talking about. Without the NES the PS1 NEVER would have existed and therefore NES > PS1.

NES

The first one was the NES with the GB and following models (GBP, GBC)

But then came the PSX wich change the world of videogames.

Later, came the Wii. I dont have to say much about this console.

I think theres was three big ages for the world of videogames.

There is little point me trying to argue any which way between NES, PS1 and Wii.... I suppose NES would have to win really given that so many people forget there were any consoles that came before it, even though there were dozens

Handheld is again conflicted between GameBoy and DS... though I think GameBoy wins it.
