I picked this up the day it launched but wound up storing it away in the closet to save as a Christmas gift for the whole family. My son and I finally got to dive into it yesterday afternoon. First impression was that it's a no-brainer purchase for $20, as you'll have one zapper shell from this buy, and presumably will pick up a second in the House of the Dead bundle, so you'll be set for two player rail-shooters without having to pick up a dupe of any of the games by buying one bundle twice.
After extended use though, I think the Zapper is a completely unnecessary accessory, or at least a poorly designed one. It was unquestionably designed by toy makers, without thought to how a real firearm should feel in your hands.
The double-grip rifle design is not only NOT ergonomic, but the particular shell design they went with has the hands too close together. IMHO, the shell needed another 2-3" down the center to space the hands further apart, preferably with one slightly offset, and/or alternately have just dropped the Nunchuk entirely and built a joystick permanently into the shell so it's easier/quicker to mount, seeing as with the package assembled you cannot use the C or Z buttons anyway.
The whole design just "feels" off to me. I thought it took some getting used to, and even after an hour it was still awkward. Most gamers are comfortable with their left thumb driving a thumbstick, and most pistoleers, riflemen, or even paintballers would use their right hand to trigger their weapon. So, while the Zapper has that part correct, having your hands reversed with the right hand in front for the Tommy gun style stacked fore-grip is counter-intuitive to how right handed people, and even a number of lefties, actually hold a real weapon, so the end result is clumsy. If you switch your handling so the grip feels natural, you're now faced with triggering with the left pointer finger while steering with the right, which is worse.
Personally, I would prefer a single-handed 45-handgun style shell for my right hand with a trigger to trip the B button, and a wireless Nunchuk for my left hand.
Or better yet, I'd just prefer two hand gun shells and no Nunchuk at all, so I can go John Woo on some Zombies.
