Anyone who has tried the original Circle Pad Pro with their '3DS Lites' will already have the general gist of what this model offers, but there are some key differences to consider. Like before, the Circle Pad Pro works through IR sensors and a single AAA battery that comes in the box, attaching itself to the receiver along the top for the signal and around the entire base of the unit for stability. Also like before, attaching the XL Pro to your jumbo handheld (this time with a sturdy and satisfying click it has to be said) blocks off some of the areas of the unit including the stylus slot, SD Card slot, Game Card bay, and Wi-Fi switch; easy to regain access to by gently slipping the machine out of the Pro but slightly annoying to have to do so nonetheless.
This time around, however, the Circle Pad Pro looks to have been designed around the XL's form factor instead of presumably a bolted-on peace offering to secure Monster Hunter like the original model was. To look at the Pro on its own would definitely give the impression of a gigantic unwieldy device, but when clipped onto a 3DS XL and put into action, the narrowed-down and slimmer sides (when comparing the aesthetics of this version to the original, at least) means that the XL's overall width is barely increased at all, and whilst the XL alone is far more comfortable to hold than its lighter predecessor anyway, the grips that the XL Pro offers are still great for a long amount of play time, if a less portable one due to the volume increase. On the original 3DS, the power and Wi-Fi lights were blocked from view because of their placement on the sides of the unit, but because of the wrapped nature of their indicators on the XL they can now clearly be seen. Even the ZL and ZR triggers look to be more improved, pressing inwards with a satisfying amount of pressure not unlike the equivalent triggers on the Wii U GamePad itself.
What really determines the worth of an accessory is, of course, the games it can work with, and although there isn't a great deal of games in the pipeline known of, the top titles on 3DS that already support the Pro are definitely worth trying it with. Metal Gear Solid 3D: Snake Eater, in particular, is incredibly difficult to adjust to without the attachment, and Kid Icarus: Uprising's left hand mode and Kingdom Hearts 3D: Dream Drop Distance's greater camera control are welcome additions.
