Gamecube, for Wind Waker and Twilight Princess, Tales of Symphonia, Skies of Arcadia, and Soulcalibur II, among other games. I was incredibly disappointed with the N64, so I was a bit shocked about how much I enjoyed the Gamecube. One or two years I bought more games for it than PS2.
PS3. I got mine after Valkyria Chronicles released and it got good games for the next 5 years.
