I have the exact opposite reaction. Civ5, Darkest Dungeon, Cities Skylines, Sunless Sea, Deus Ex, HL, FTL, Total War, System Shock 2, Fallout, and the myriad of other mouse and keyboard games are now playable with a controller. That defines fixing a problem in terms of playing in the lounge or anywhere else without have to have both a mouse and keyboard solution, which is cumbersome without a desk solution. Attempting to play these games with a traditional Controller is a broken experience. Playing TF2, CSGO etc and actually having a playable experience while being competent is huge for being able to have PC gaming not be confined to a desk. The added bonus of having close to mouse / trackball movement in current controller centric games is also pretty damn great as it improves the experience easily. MGSGZ for me is the prime example of why mouse like control and precision for aiming and turning is far better than an analogue stick. Movement flexibility is where analogue sticks shine, but it wouldn't surprise me to hear that the track pads can emulate that well once a person is accustomed to it, as some of the GAF testers have said.
Crowd sourced binding and complete flexibility to customise the controller to a game and individual needs is exactly the kind of solution suited to PC gaming. In the end this is what it is all about - PC gaming - which needs this solution to not require a form of desk, but also isn't enforced as a standard in keeping with the flexibility and choice individuals have when using PCs.
