1. Duck Hunt
But Duck Hunt is already a shooting game, you yell at your screen. What are you trying to get at with this? That would be a solution to the age-old problem of not being able to shoot the one thing most gamers wanted to shoot most: that damned dog. Take the ducks out altogether and replace them with dozens upon dozens of that pesky dog. Make the gameplay similar to what it's like when someone calls in dogs in Call of Duty, except with that harmless hunting dog in place of the more rabid ones found in that game. Then throw in unlimited time and ammo and let players work out years of frustration in a never-ending bloodbath. It's perfect.
