I have had some success playing SC with the triggers and trackpads, though.
I had hoped to use the gyros for that, but I was disappointed to find that that aspec t of the software is grossly underdeveloped. I bought this to play Star Citizen, which requires six degrees of freedom. But if you're a PC gamer who is going to have a mouse and keyboard in front of you anyway then the Steam controller will probably sit unused.
If you want to experiment with an innovative input devise, or if you're just a casual gamer who wants to play on the couch, then the Steam controller is probable worth $35. It's better than any controller, but it isn't magical enough to rival a mouse. In terms of performance it is, as you might expect, somewhere between a mouse and a controller. I wish that it had standalone software a la the Steelseries engine. Of course, it does require all games to be run through Steam's Big-Picture mode.
