More controller options are never a bad thing. You just have to complain. You'd complain that there was no Classic option if there weren't one because games like this have been done before with those controls
I'm thinking of the past when the analog stick debuted. It was a new concept that Nintendo put on their standard controller and at first the idea was kind of out there. But you sat down with Super Mario 64 and it became immediately apparent that this new analog stick was perfect for the game and was absolutely essential. And it proved to be essential for so many games that followed it.
One could at a glance have said "why don't you just have a run button like in the old Mario games"? But once you used it you knew that wasn't possible; one would need to dedicate multiple run buttons for various different speeds. It just wouldn't work and Super Mario 64 DS tried offering a run button and it was a mess.
Maybe the analog stick just raised my expectations so high but when Nintendo says stuff like "this is going to be the new controller standard" those are big words and they've got to prove that to me. That's just for the regular remote. Motion+ is another step up and it requires an additional purchase. One would assume that Motion+ would provide certain control possibilities that would be impossible to implement with a traditional controller or even the bare-bones remote. Otherwise it just seems so pointless to me. If you're going to make it work with traditional controls as well it suggests to me that you're not fully exploring the possibilities that Motion+ should provide. And if we're buying this controller add-on shouldn't we expect them to go for broke with it?
I'm not looking for a different way to do the same thing a traditional controller already does. It was never broke, so I don't need it fixed. When you're talking about new standards and innovation, sorry, you have to provide me with something truly substantial. Otherwise you're full of **** and you're just a flim-flam con-man trying to rip me off.
I think it has to be a "this could not possibly be done any other way" situation and in that case you just couldn't offer the traditional option. It wouldn't work.
