Chicken Invaders 3 Christmas Edition is my first pick for games to get before Christmas. If you eat chicken (grilled, roasted, stewed, you name it), eventually they will come and invade the Earth – enjoyable shooting ahead. Game Club pass owners can get the game as low as $6.99. Chicken hamburger meals can cost more than that.

Chicken Rush game shows how casual games bring action in games. Instead of shooting horrible zombies, or creating frightening atmosphere – the game puts dozens and dozes of enemies in front of you. With Game Club pass it costs only $6.99.

Both of these games rely on very, very simple game mechanism – put tons of stuff to handle – and pack it for sale. How’s that for a recipe about making a successful game?
