Wiiiiiiiiiiiiiiii. Lots of great Nintendo classics, Zack & Wiki, an actually good Sonic game, Trauma Center and New Blood, Nights, the first No More Heroes, among others.
Still really like the Wiimote and Nunchuck, the main flaw with the system is that it spawned Dawn of the New World.
Followed by the 360. Tales of Vesperia, introduced me to Dead Rising (RIP since 2), enjoyed my time with Halo, Ninja Gaiden, Guardian Heroes, and more.
PS3 last. As much as I love the Atelier Dusk and Arland trilogies, the solid Tales of from it and others, I hate the system itself, its interface, and the controller.
