more memories

Here, one can see the graphical prowess that is the Intellivision. In the upper left-hand corner is a picture of the game I constantly lost at- the MLB game.
In the bottom left-hand corner is the NFL football game. I remember that you had to punch in four numbers to select the play you wanted from the included playbook. There was one play that was either 9929 or 9949 where you could drop the QB back however far you wanted as long as you went towards the upper sideline, but not too close. Then, you could pass and the ball would ever so slightly veer towards the upper sideline and your WR would catch the ball 99% of the time. There was that 1% that the ball would be intercepted or go out of bounds.
A later version, Super Pro Football, allowed you to play against the CPU and it had a shadow under the ball to give the illusion of height/depth.
Both of the original MLB and NFL games required two humans playing, as did all of the original sports games.
