9. Duck Hunt
God bless Nintendo for coming up with the Zapper was gaming brilliance at its zenith and the company did its utmost to cash upon this golden goose without slaughtering it. The game can best be described in the misquotation that is oft attributed to Sherlock 'Elementary, my dear Watson.' Duck Hunt was gaming at its simplistic best. Flying ducks that have to be shot, the Zapper that lets stretch your arm out and take aim and points received for every dead duck. A highly memorable and annoying soundtrack topped it off. And there was a dog, who served no real purpose than be eye-candy, bear a ridiculous grin and pull the ducks out every time you shot them. The game went on, ad nauseum, till either the NES burnt out or you fainted due to thirst and hunger. The best part, beyond a wisp of a doubt, was the actual ability to aim and shoot with the gun in your hand. It let you get as close to reality as games had enabled players to so far. People positioned their feet and titled their heads at an angle just so that they could get a better aim. That's the level of engagement the Zapper created amongst players. It was the ultimate stress buster; and ever since the game went out of circulation, stress hasn't been busted as hard.
