I've had 3 controllers since the GCN was introduced. The first one's analog stick is very loose for some reason, and I hadn't even heard of dash-dancing until recently, and never was too good at it. It's too loose now for serious use (although it still works, I just don't like using loose control sticks), but I keep it anyways. It was the first controller I've used. The second one I've used still is in entirely working order, but the stick is somewhat loose in the upwards direction, and only slightly loose in other directions, most likely because all I've really played for the good duration of the GCN's hey-day were 3D Adventure games.
I've never bought a single extra controller since the three I bought slightly after SSBM came out, but I've been using the third one exclusively for at least 3 years now, and it's hardly if at all loose in the four cardinal directions, but not at all noticable unless you're trying to see if it's loose or not.
I guess I was really too young when I first bought my GCN, and maybe I believed that the harder I pushed, the faster it'd go. D:
Luckily, I discovered that it didn't work that way after the first controller went loose, so meh.
