In order:
Nintendo GameCube - Mario Party 7 (was a kid)
Nintendo DS - The console itself
Wii - Mario Party 8 (xD)
Xbox 360 - Gears of War 2
PlayStation 2 - Ico
Wii U - Pikmin 3
PSVita - Tearaway (and still have to buy the console and the game)
Xbox One - Gears of War and Halo 5, not very attracted to it yet...
PlayStation 4 - Tearaway Unfolded and Uncharted 4, nothing more.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
