Sounds to me like you're comparing apples to oranges. Input method has nothing to do with why console games only allow adjusting gamma and contrast, that's because on a console the game is already optimised for the exact hardware as it only runs on one type of hardware, so you get almost no options because none are needed beyond things like whether or not you prefer motion blur, etc. But my argument was that in the actual game Portal not many inputs are even needed, which you didn't even respond to... The one thing that differs in the "analog stick" argument between controller and mouse is that the mouse offers much more flexible movement than the controller. You can only angle the controller at most 30° and that's it, while you can throw your mouse across your desk if you want to. This I could accept does theoretically limit design a little bit if you are aiming for an enjoyable controller experience in a fast-paced game where you're utilising all 3 axes in movement. But Portal is not a fast-paced game so that doesn't really apply...
