I have been a fan of the Madden NFL series for a very long time. The game has taught me much about the rules and strategy of American football. Early versions of the game allowed you to run plays in a training mode with John Madden instructing the player exactly how the play was going to be run and explaining the terminologies. Later editions allowed you to design your own unique plays that you can use in the game. I never was very good designing my own plays, but it was fun to try to be the coach of my favorite team.
