A great package with the system
Duck Hunt utilized another device, the gun. Few games actually used the gun, but it really worked. You have the option of going after 1 duck, 2 ducks, or 2 clay disks. If you missed the disks, there was no problem. If you missed a duck, the stupid dog would laugh at you. You can always cheat by sitting up close, but the game is much better played when you try to play for real. There is no real objective other than to get the high score.
Both games were great, but there was also an edition with the powerpad and Track & Field. While that package was great, I had enough fun with these two games.
