Just like the title says.

^and PS3 is reliable

SNES, had many of the best games I´ve played.

The PS2.

That game library was magnificent. You could have 60 games, all excellent. If you were willing to go a notch down, to very good, you could have well over 300. It will have the best library on a console for a LONG time. There was Final Fantasy, Tekken, God of War, Ratchet and Clank, Jak, ICO, Shadow of the Colossus, Devil May Cry...

Wow. If you ask me, it deserved MORE than 120 million sales.

PC, games on other systems do not really require much thinking and are mainly brainless shooters or arcade games. I do also like how you can play older games with newer rigs and they will look much better than last time you played them. :)

Not to mention biggest & meanest game library including games from arcade machines and older gaming machines.

Wii

it's just a hell of a lot more fun

Runner up PC

At the moment, PS1... but my PS3 is quickly catching it, a couple of platformers and beat 'em ups, and I'll have a great, well-rounded collection of games that I love.
