I want to know the answer to the following question:
What game accessory was similar to the NES Advantage?
All the background I'm provided with is that "Many of these devices were modeled after earlier add-ons for the NES: the Super Scope is a light gun functionally similar to the NES Zapper (though the Super Scope features wireless capabilities) and the Super Advantage is an arcade-style joystick with adjustable turbo settings akin to the NES Advantage.". Is that enough to answer the question?
Answer: yes
