Some people count Gears of War to the fps genre. They should count Duck Hunt as an fps as well.
It would be quite funny having Duck Hunt as the best selling fps of all time, would sure as hell piss a lot of ''hardcore gamers'' off.

Wow, I would collapse over in exhaustion if I had to list everything wrong with this post.
