I once again find myself unable to tangle through incorrect terminology and ask the right questions. Let me try again:

I had a terrible experience playing a Twilight Princess demo. The controls were absolutely wretched. Is this an issue with the game, or the Wii?

And actually, all I can play are the games they happen to have on display at the stores, as I don't have a Wii yet. I'm saving up for one, though, and I just want to make sure I won't be wasting my money on a shitty system that has a controller with all the control prowess of the Powerglove.
