and that's never happened with any new control scheme? Dual analog controls are flawed, and those of us from PC land had to adapt to the limitations the controls present. Yes I am comfortable using them for most games now, but I still avoid non-military FPS's on consoles as aiming ahead w/ rockets or keeping a laser trained on an opposing team for several seconds while they jump around is extremely cumbersome for me using analog controls.
The only difference between those FPS's and KI's situation I believe, is that mass exodus from the PC games market forced a lot of people to adopt dual analog controls while implementations like KI/Metroid Hunters are rare one-offs. Both are perfectly adaptable for most people, but unless it becomes a de facto standard the common double standard of gamers -- no wait, of everyone, with pretty much everything -- to wish for innovation (and yes, dual analogs was an innovation too -- who woulda thought you could get a shooter experience sitting on your couch?!) while bashing the fucking bejesus out of it until it becomes commonplace.
