Xbox 360 - Still to this day an amazing controller. Halo games galore.
PS4 - Far cheaper than PS3 despite inflation, yet many more appealing games to me. This is the closest I've ever been to buying a PlayStation.
GameCube - Best controller of all time. I could fall asleep holding that thing it's so comfortable. Melee, Rogue Squadron 2, Starfox Adventures, Animal Crossing, Luigi's Mansion. So many good, first time games on that device. Many ips started here.
