I think there's a risk of diluting what we have if we go delving into making the gadgets. There's also really no need to.
The watch laser in GoldenEye 007 was very specifically made for the Train level, it's pretty agreeable that not much went into it as it was just the Detonator watch with Moonraker lasers coming out of it with limited range.
Having said that I don't see how it fits in with the scope of our mulitplayer. Much like the Taserboy, it doesn't really know where to fit in, or even have a good reason to.
