PS2 = Great, third best console ever.
PS1, PS3, PSP and all other Sony games consoles = Not the same touch as PS2, not nearly as good. PS1 is ok though.
NES = It's ok, it has nice sounding music and the graphics look cool, it also introduced loads of great games like Mario Bros. Don't own one so can't say much 'bout it.
SNES = The best console ever made. 'Nuff said.
N64 = Brilliant, graphics are perfect because the quality is between the PS1 and PS2 and has the fuzzy TV feel to it, Goldeneye, Super Mario 64 and many more. Second best console ever. I have spent many hours on it.
Gamecube = Ok, some games are good, has a nice controller, I never play much on it though,
Wii = Not as good, first Nintendo console to loose the classic feel, gamecube almost did. I never owned a Wii myself but theres something about it, it might be that you have to put batteries in the remote and configure everything and the default colour is white rather than black and it focuses on HD rather than the fuzzy TV, but that new feel to it is what ruined it for me. It doesn't feel like a Nintendo console.
