Controllers today are designed to function in a certain way. And I think it works pretty well. The way it grips, the way your have access to the buttons. I'm finding it difficult to justify the need to play this way. If the controller scheme is that technical and complicated, I think there may be something fundamentally wrong with the controls, not the controller. Or if you're going to make something that complicated, at least man up and make a bad ass mega-mech controller for it.
Now this is a proper Mecha ControllerI dunno. To me... It somehow feels dirty. Like you're not supposed to grab a controller that way. And I don't know why.. But this T-Shirt(kinda NSFW) came to mind.
