You'd be surprised at how many don't. I have a little Windows box connected to my TV right now, with a $10 Xbox controller wireless receiver. Steam runs in Big Picture mode, and I'd say that somewhere between a third and a half of my games play great with a controller. I've been doing most of my gaming that way lately, and it's a very nice experience.
