This new analog attachment complicates things for more than just players; it complicates things for developers. I think I can safely say that is one of the few good articles written on IGN.com in the history of its existence.
This is a pretty good summary.
Quote:It's not that the Nintendo 3DS is necessarily doomed without a second analog stick. Had Nintendo never mentioned the idea, it could have likely made do. Some games developers would have probably passed the system by in favor of the Vita, but even Monster Hunter survived without two analog inputs – look at the PSP versions. But Nintendo decided to open that door. It has now openly suggested its launch hardware design is flawed. It's introducing an awkward patch to a portable design that is clearly inadequate in its own eyes.
This is a pretty good summary.
