Duck Hunt is an amazingly simple and quite addictive action style game. Just go out hunting for Drakes and shoot as many of them as you can. You have to be pretty quick because the time is limited up to three minutes only (for the full version). The more ducks you manage to kill the more points you are going to receive.
Duck Hunt can be purchased here for $9.99, so if you have any violent tendencies, head on over.
