Sometimes, mostly when either some console broke/got unavailable (I moved around the globe but couldn't take all my consoles with me) or rarely, if I got a game on PC and really needs a gamepad (or on consoles and could benefit from Mouse+Keyboard, but that only happened once yet). All in all, that's about 15 games total, not counting Super Mario Allstars and Super Mario Advance (aka SMB2; got both games as pack-ins)
