I really dont think theres such think as a video game being "not worth it" when it costs 5 bucks....
Yeah there is. I bought my kid an M&M's game for the wii. It was unplayable. You drove a car, it'd get stuck on a wall or some other object and it'd take you a minute or two to get the car off the obstacle. Half the time the effort of getting unstuck got you stuck on another object.
That was a waste of $5. Costco took it back though.
