I am player one.
Life has no 1-ups or saves.
If only it did.
In some video games, much like real life, there are harsh consequences for making mistakes. Players may lose items, miss opportunities, or even die. Unlike life, however, games have built in ways to try again, either by 1-ups (brings you back to life), or save points which bring you back to previous points in the game.
I can look back and see many times in my life where I would like to take more risks or go back and make better choices. Sometimes this player one wishes he could just restart the game.
