The optional bolt-on attachment for 3DS comes with the need for additional juice for power, but just how long would it last?
According to an eager owner of the new Circle Pad Pro, the included instructional leaflet from Nintendo suggests that a single AAA battery would be enough to provide around 480 hours of use - a good few weeks for the average gamer, or twenty days for the non-stop 3DS monster.
The extra control stick adds an additional means of controlling characters and camera on screen, ideal for adventure games, first-person shooters and platformers - but comes at the cost of having to screw the attachment onto the back of the 3DS. The battery slots inside a screwed compartment - meaning you'll have to remove the Circle Pad Pro, unscrew, to replace the battery.
What do you think of the peripheral? Is it needed? Should Nintendo have included a second Circle Pad at the start?
